It would be best if you could talk to mirv on IRC about this.
But IMHO it is the wrong approach.
Because if I understood you correctly it means to compute the position
and orientation
of every vertex for every model per frame on the CPU.

The only vertex buffer should be the model data.
Then you add the MVP matrix, the time offset into the animation and the
position/orientation data of the animation as uniforms and let it all
compute
in a vertex shader.
This way only the MVP matrix and the time offset changes per animation
frame.
