Asked my friend about her body, she said a friend made it and it isn't something that's being sold currently. My mesh body was made using avastar which is a blender addon for making avatar meshes. I fed it an xml dump of my shape, carefully carved out the face portions and the ears, and uploaded the resulting mesh. I fed it a skin that was partially transparent and used a the blank texture as the spec map under the new materials system. This allowed me to put shininess on a transparent object, but only to those with advanced lighting enabled.
If you snag avatar workbench you can get similar results to my work, but it takes a lot more hand tuning and finagling to get the mesh upload close enough to your avatar. Avastar really simplifies the task and adds some handy tools.
Fortunately both are an addon to Blender, which is quite free.
Also, sorry for the delay in response, I kept forgetting about the question whenever I was talking with the friend in question.
