The system of claim 5 wherein said housing is elongated and generally cylindrical and is comprised of a material that is resiliently squeezable along the entire length of the housing. 7. The system of claim 5 wherein said housing is elongated and generally cylindrical with a bulbous outwardly convex portion that is resiliently squeezably compressible. 8. The system of claim 5 wherein said housing is elongated and generally cylindrical with only a small portion of said housing being resiliently compressible. 9. The system of claim 1 wherein said transfer means comprises a solid body having at least one capillary passage defined longitudinally therethough in communication between said enclosed volume and said nib. 10. The system of claim 9 wherein said housing is elongated and generally cylindrical and is comprised of a material that is resiliently squeezable along the entire length of the housing. 11. The system of claim 9 wherein said housing is elongated and generally cylindrical with a bulbous outwardly convex portion that is resiliently squeezably compressible. 12. The system of claim 9 wherein said housing is elongated and generally cylindrical with only a small portion of said housing being resiliently compressible. 13. The system of claim 1 wherein said transfer means comprises a solid body having a plurality of capillary passages defined longitudinally therethough in communication between said enclosed volume and said nib. 14. The system of claim 13 wherein said aspiration means comprises porosity in said nib. 15. The system of claim 1 further comprising aspiration means for permitting entry of ambient air into said enclosed volume in response to the pressure in said enclosed volume dropping below ambient pressure. 16. The system of claim 15 wherein said aspiration means comprises a channel defined in the periphery of said nib. 17. The system of claim 15 wherein said aspiration means comprises a channel defined in a portion of the housing surrounding said nib. 18. The system of claim 15 wherein said aspiration means comprises a longitudinally extending bore defined in an interior surface of an end piece securing the nib to the housing. 19. A method of providing controllable delivery of marker liquid to a surface to be marked, said method comprising the steps of: (a) disposing the marking fluid in a selectively pressurizable container defining an enclosed volume; (b) securing a porous nib to a distal end of said container; (c) resistively blocking flow of the marker liquid to said porous nib in the absence of pressurization of said enclosed volume to a predetermined level above ambient pressure; and (d) in response to pressurizing said enclosed volume to said predetermined level, delivering capillary flow of the contained marker liquid from said enclosed volume to said nib. 20. The method of claim 19 wherein step (a) comprises disposing the marker fluid in a squeezably compressible container to permit pressurizing of the enclosed volume to be effected by squeezing the container. 21. The method of claim 20 wherein pressurization of the enclosed volume is effected by a user blowing into the container.
