Well... there is the Avatar 2 ruth/ roth avatar. which is an open source mesh avi, complete with hud and scripts that's is used in Opensim and other grids.
How the hell.. lol thats a big question.
But basically, you get an avi, you cut it into little pieces and shove a texture alpha trigger script in the root prim. Then, you take a duplicate of that avi and put in a texture alpha trigger script and attach it as a HUD. Tadaaa! yYou very own Mesh Body.
Edit: If you ask Zero very nicely, maybe she will give you a copy of the simulated baby avi she made
