new game-menu option 'Record Game Physics to Ipo'

including implementation. hope it works, and doesn't break to much.
it bakes physics objects transform into ipo, every frame of the running gameengine.
When you disable and run the game again, it clears the ipo's again. just for physics objects at the moment.

(perhaps some better UI in the future?)
