Whatever, I do have dev access on JOODE, which means KOWA-BUNGA !! I CAN DO WHATEVER I WANT...
Err.. whatever is good, at least

OK. And you know how to use JOODE (other than me

).
Is there a way to indroduce some interfaces, that the collision system classes of JOODE should implement, that could be shiped in a separate JAR? These interfaces could then be used by xith to attach a collision node (or whatever) to xith nodes. And voila, we could finally waste the xith internal collision system and the existing isCollidable() setCollidable() methods and what ever else exists for the current xith collision system could forward to the methods behind the JOODE collsion interfaces.
Wouldn't that be cool

.
I guess the physics engine shoudn't be hardlinked with xith or even can't be. It's just another thing. And works great, if set on top of xith, doesn't it?
