Sorry to step in but you can distribute faces created in the FaceRoom very easily and without any legal problems by creating a .fc2 file with the FR data.

Sometime ago Dead_Reckoning, semidieu and I were playing with this kind of stuff, it is simple and it has many advantages like a .fc2 file is like 200 kb and a head morph is close to 9 Mb in case of Miki for example.

semidieu included this function in Shaderworks a little but powerful application. You can find it here: http://poser.rois-sorciers.com/ShaderWorks/download.html
