The invention claimed is: 1. An inline valve comprising: a housing; a metal choke member in operable communication with the housing, a portion of the choke member being substantially immobile relative to the housing and a portion of the choke member being mobile relative to the housing, the choke member itself being interactive with a target tubular and having no other sealing member interposed between the metal choke member and the target tubular; an actuator in operable communication with the movable portion of the choke member, the actuator selectively causing the metal choke member to deform radially. 2. The inline valve as claimed in claim 1, wherein the choke member includes a fixed attachment to the housing. 3. The inline valve as claimed in claim 2, wherein the fixed attachment is a rod. 4. The inline valve as claimed in claim 2, wherein the fixed attachment is central of the inline valve. 5. The inline valve as claimed in claim 1, wherein the choke member is in pressure sealed communication with the housing. 6. The inline valve as claimed in claim 5, wherein the pressure sealed communication is a piston arrangement where the piston is connected to the movable portion of the choke member, the piston being movable within the housing. 7. The inline valve as claimed in claim 6, wherein the piston is connected to the choke member such that a choke segment of the choke member deforms upon movement of the piston. 8. The inline valve of claim 1, wherein the actuator is a pressure based actuator. 9. The inline valve as claimed in claim 1, wherein the actuator is a motor based actuator. 10. The inline valve of claim 1, wherein the choke member includes a choke segment that is predisposed to deform radially upon the application of an axial compressive force thereon. 11. The inline valve of claim 10, wherein the choke segment includes a plurality of lines of weakness. 12. The inline valve of claim 11, wherein the lines of weakness are positioned to create a selected profile upon deformation. 13. The inline valve of claim 11, wherein the lines of weakness are grooves. 14. The inline valve of claim 11, wherein the lines of weakness number three and are positioned two on an outside dimension of the choke segment and one on the inside dimension of the choke segment. 15. The inline valve of claim 10, wherein the choke segment is reverse hourglass shaped. 16. The inline valve of claim 10, wherein the choke segment is metal. 17. The inline valve of claim 1, wherein the movable portion of the choke member is central to the choke member. 18. The inline valve of claim 17, wherein the choke member is fixedly connected to a central attachment operable with the housing. 19. The inline valve of claim 18, wherein the central attachment is actuated by the actuator to urge the choke member in a direction calculated to cause radial deformation of a choke segment of the choke member. 20. The inline valve of claim 1, wherein the actuator includes two hydraulic inlets, one for actuation in each of two directions. 21. The inline valve of claim 19, wherein the attachment includes a piston reactive to applied fluid pressure to move the choke member. 22. The inline valve as claimed in claim 1, wherein the choke member is a permanent barrier for well abandonment. 23. A method of choking a tubular, comprising: energizing an actuator in operable communication with a movable portion of a metal choke member; moving the movable portion relative to a substantially immobile portion of the choke member causing a metal choke segment of the choke member to change a radial dimension thereof; and choking an available flow area with the change in the radial dimension of the choke member, the choke member itself being interactive with the tubular and having no other sealing member interposed between the metal choke member and the tubular. 24. The method of choking a tubular of claim 23, wherein the energizing further comprises pressurizing a chamber to move a piston in operable communication with the movable portion. 25. The method of choking a tubular of claim 24, wherein the pressurizing a chamber further comprises building pressure through heat energy input. 26. The method of choking a tubular of claim 23, wherein the energizing further comprises rotating a motor. 27. The method of choking a tubular of claim 23, wherein the radial dimensional change of the choke segment is a radial increase and the choking is between the radial increase of the choke segment and an inner wall of the tubular. 28. The method of choking a tubular of claim 27, wherein the choking further comprises sealing the choke segment to the inner wall of the tubular. 29. The method of choking a tubular of claim 23, wherein the choking of the flow area is reversible. 30. The method of choking a tubular of claim 23, wherein the choke member is made of an erosion resistant material. 31. The method of choking a tubular of claim 23, wherein the choke member is coated with an erosion resistant material.
