What is claimed is: 1. A system for providing flexibility in a gas delivery pathway of a mask apparatus, comprising: a first housing portion; a first rim defined by a seal ring and flexibly coupled to the first housing portion by a flexible member, said flexible member comprising a flexible support ring configured to support the seal ring in the first housing portion; wherein the flexible support ring comprises a circular ring with inner and outer layers to form a U-shaped cross-section, said U-shaped cross-section configured to provide a resilient force; a second housing portion coupled to the first housing portion; a second rim associated with the second housing portion; and a ball rotatably disposed between the first and second rims and maintained in contact with both the first and second rims by a resiliency of the flexible member, the ball having a gas passageway extending therethrough. 2. A system according to claim 1, wherein the first housing portion is configured to be coupled to a first gas delivery conduit and the ball is configured to be coupled to a second gas delivery conduit such that a pathway is formed through the first gas delivery conduit, the ball, the first housing portion, and the second gas delivery conduit. 3. A system according to claim 1, wherein the ball comprises: a ball body comprising a hollow cylinder having a continuous interior surface and a first hemispherical portion extending from a first end of the cylinder toward a second end of the cylinder; and a ball cap comprising a second hemispherical portion having an opening configured to receive the hollow cylinder, the second hemispherical portion configured to abut the first hemispherical portion such that the first and second hemispherical portions form a ball, the gas passageway extending through the ball. 4. A system according to claim 1, wherein the first and second rims maintained in contact with the ball are circular such that the first and second rims form two seals against the ball. 5. A system according to claim 1, wherein the second rim is integral with the second housing portion. 6. A system according to claim 1, wherein the first rim is integral with the flexible member. 7. A system according to claim 1, wherein: the flexible support ring is formed from a first material; and the seal ring is formed from a second first material having a lower coefficient of friction than the first material. 8. A system according to claim 1, wherein the flexible support ring is coupled to the first housing portion and provides a resilient force that resists displacement of the seal ring in a first direction extending into the first housing portion. 9. A system according to claim 8, wherein the ball displaces the seal ring in the first direction. 10. A system according to claim 1, wherein the second housing portion comprises a cap that screws onto the first housing portion. 11. A system according to claim 1, wherein the second housing portion defines the second rim. 12. A gas delivery mask apparatus, comprising: a first gas delivery conduit; a second gas delivery conduit; and a joint coupling the first gas delivery conduit with the second gas delivery conduit, the joint including: a first housing portion; a first rim defined by a seal ring and flexibly coupled to the first housing portion by a flexible member, said flexible member comprising a flexible support ring configured to support the seal ring in the first housing portion; wherein the flexible support ring comprises a circular ring with inner and outer layers to form a U-shaped cross-section, said U-shaped cross-section configured to provide a resilient force; a second housing portion coupled to the first housing portion; a second rim associated with the second housing portion; and a ball rotatably disposed between the first and second rims and maintained in contact with both the first and second rims by a resiliency of the flexible member, the ball having a gas passageway extending therethrough. 13. A mask apparatus according to claim 12, wherein the first housing portion is configured to be coupled to the first gas delivery conduit and the ball is configured to be coupled to the second gas delivery conduit such that a pathway is formed through the first gas delivery conduit, the ball, the first housing portion, and the second gas delivery conduit. 14. A mask apparatus according to claim 12, wherein the ball comprises: a ball body comprising a hollow cylinder having a continuous interior surface and a first hemispherical portion extending from a first end of the cylinder toward a second end of the cylinder; and a ball cap comprising a second hemispherical portion having an opening configured to receive the hollow cylinder, the second hemispherical portion configured to abut the first hemispherical portion such that the first and second hemispherical portions form a ball, the gas passageway extending through the ball. 15. A mask apparatus according to claim 12, wherein the first and second rims maintained in contact with the ball are circular such that the first and second rims form two seals against the ball. 16. A mask apparatus according to claim 12, wherein: the flexible support ring is formed from a first material; and the seal ring is formed from a second material having a lower coefficient of friction than the first material. 17. A mask apparatus according to claim 12, wherein the flexible support ring is coupled to the first housing portion and provides a resilient force that resists displacement of the seal ring in a first direction extending into the first housing portion. 18. A mask apparatus according to claim 17, wherein the ball displaces the seal ring in the first direction. 19. A system for providing flexibility in a gas delivery pathway of a mask apparatus, comprising: a first housing means; a first sealing means flexibly coupled to the first housing means by a flexible support means; wherein the flexible support means comprises a circular ring with inner and outer layers to form a U-shaped cross-section, said U-shaped cross-section configured to provide a resilient force; a second housing means coupled to the first housing means; a second sealing means associated with the second housing means; and a ball means rotatably disposed between the first and second sealing means and maintained in contact with both the first and second sealing means by a resiliency of the flexible support means, the ball means having a gas passageway extending therethrough. 20. A breathing facilitation system for facilitating or affecting a subject's breathing, comprising: a gas source configured to deliver gas; an adjustable mask apparatus; and one or more gas delivery conduits configured to deliver gas from the gas source to a subject via the adjustable mask apparatus; wherein the adjustable mask apparatus comprises a gas pathway flexibility system, comprising: a first housing portion; a first rim defined by a seal ring and flexibly coupled to the first housing portion by a flexible member, said flexible member comprising a flexible support ring configured to support the seal ring in the first housing portion; wherein the flexible support ring comprises a circular ring with inner and outer layers to form a U-shaped cross-section, said U-shaped cross-section configured to provide a resilient force; a second housing portion coupled to the first housing portion; a second rim associated with the second housing portion; and a ball rotatably disposed between the first and second rims and maintained in contact with both the first and second rims by a resiliency of the flexible member, the ball having a gas passageway extending therethrough.
