copy an armature bone on each vertex

Did someone know a script that copy a bone on each vertex of a mesh. i need to do a stop motion like deformation but shape keys got a spline interpolation.

Hallo dagobert,
Your wish is very strange, probably because I do not understood totally.

As far as I know, jou can NOT parent vertices to a bone.
So what do you really want ???
(evtl. help from me only for Blender 2.53)

sorry for the long delay. the trouble is solved in 2.5 because shape keys supports dfferents interpolation mode.
