I don't know how to dificult whould be to implement a feature like this one, but I have an idea to share with somebody interested:
Imagine an armature with 2 bones (3 if you count the used for IK) the number 1 is the root and the number 2 is the children.
Imagine a limit of 90 degrees for the child.
Now we grab the control empty and move to the root bone.
All the system is working like ever, but when the child bone reaches 90 degrees or more (in respect to root bone), then a new empty is created (internally) on the same Loc where child bone is, and a new IK constraint is created (again internally) pointing to the new empty.
This status is keep while the first bone move in the range of the limit zone (more than 90 degrees).
Uffff!!!
Sure no one understand me

P.D: ARG!! Some day I sould to learn english
