Unable to pose rigged hose or keyframe it I'm new to rigging, so hopefully these errors aren't glaring :)  I'm trying to pose this hose and keyframe it, but the hose warps when I move the bones (I used a curve with IK spline for the bones).  Also, I'm not able to keyframe it.

Here's the resting pose:



Here's what happens when I try to move it:



I've attached the .blend
Unfortunately, bezier curve control points themselves are not keyframe-able.  You can, however, make a "hook" to those control points by selecting them in edit mode and pressing ctrl+h.  The hooks created this way are keyframe-able, and should give you the level of control you are looking for.
