Hello Ross,
Sorry for this very very late response but been a bit busy last
months!
At the moment I guess there's about 20% (in from what will be possible
in the end.
Try to look at the demos at the svn, you will find most current
features in there.
Also you might want to look at bullet physic at
http://bulletphysics.org/
Lot of info and documentation over there.
Good luck!
Cheers,
Ringo.
