What we're experimenting with is putting assets under version control 
(using subversion, of course) as binary otl files. Everyone sources 
their own working copy, and commit/update regularly to stay in touch 
with the rest of the crew.

hip files are less and less important. If you want an piece of animation 
to be placed under version control you wrap it into an asset and commit 
the .otl to the repository.

So it's not just tools / shaders/ rigs under version control.. 
sh01_girl_talking would be an outer wrapper asset containing an instance 
of girl_face_rig asset with keyframes applied. The .otl containing 
sh01_girl_talking contains the keyframes which are thusly version 
controlled... yeah!?!

This is pretty experimental at this stage, but holds a lot of promise.
