If we could remove the restarts of the interpreters that would work.
I heard of some dictionary hacks in old versions, where BPY and GamePY
were both avaible. I have to seek through cvs to figure out what happend
there clearly...

Hm, and what if the game engine is restarted? Stopping an stay means the
scene converter couldn't be ended, that will give great confusion I guess.

Maybe someone likes to test the patch?

In the old implementation of my application I did just that. Mesh replacement
with BPY and then restart of gamescenes and so on. But with new bpython
implementation it was removed from game appearence :-(. So I started my
research on better cooperation of the both pythons.
