One Avatar, Many Worlds
This will be useful. Personally I don’t like the avatars in Second Life - I’d rather be represented by an abstract concept. 
“DAZ 3D, a company based in Draper, UT, that makes software and models for creating 3-D art, recently announced the MogBox, a program that would allow users to design a high-resolution 3-D character and transport it as an avatar to multiple virtual worlds. MogBox is designed to maintain the same look and feel for the character from one location to another, while adjusting for the graphics capabilities and styles of different virtual worlds.”
