Hi everyone,

V-Ray is going to release a new Vray-Blender version. It's based on 
linking via a protocol (to send data over). It's meant to be compatible 
with the GPL.

Since I'm not an expert, people might be interested in looking at how it 
was done.
It's very nice to have their sources anyway. Good practice to share that 
with us!
