bullet physics engine?

[smallville]

i don't know if the bullet physics engine is getting implemented into GE, but what would be really useful would be a physics engine, for simulating
rigid body's and and maybe (if possible) soft body's. of course with softbodys there is the problem of having to squash, bend, stretch and distort the sprite or animation.

for example if you have seen the game demo called 'GORGAR!' by dst ( http://game-editor.com/forum/viewtopic.php?f=6&t=5686 ) this is a very well done example of 'destructible' buildings, now if there was a rigid body simulator, this could be so much better. but dst did a great job just working with what he had.

but also would it be possible to import a C code into GE's global code and set a '(rigid == 1);) or something like that?
or would it be possible to port a script (with permission) that simulates rigid body's from another open-source software uses C++?
