That situation has been living a bit now - at 0.0.2 time some folks were 
able to log in and move in a world ok, but some time after that new 
things have introduced a crasher which is not hunted down yet. We now 
(since Thursday/Friday) have a buildbot that builds with Linux after 
each commit, and start adding it running tests too tomorrow, and 
probably get someone busy with hunting the new bug there so hopefully 
get that to good shape soon.

In ReX an avatar can use any mesh, just like any other object. And 
further the mesh can have any kind of UV layout and a skeleton for 
animation, like in Ogre and in 3d gfx in general normally.

For example in the 1 year old Beneath the Waves demo for ReX 0.4, the 
game works so that there are statues of fishes in the lobby, and you 
start by selecting the kind you want to be while playing. It then 
changes your avatar to that type of a fish for the duration of the game.
