[Bf-committers] Some Some doubt and ideas

[GeKo]

For me there two level in this issue, the first level is the way to
organize the object. One possible structure for the object could be:

One object could be:
* Inanimated (default)
* Animated:
   ** Pasive (default) interact with other objects
   ** Active :
      *** Rigid
      *** Softbody
      *** Particles
      *** Cloth

Maybe I could be clearer for the user.

The other is about to join some of the "active" object making another
more generic, but I see this much more difficult and not so important.

;) Thank for your time.
