well, I'm not an expert to interpret EULA & such, but it was a user that have multi Titan system & he offered on forum do do rendering for those who need that. OTOY approach him with comment that this is not allowed..
so, I'm not here to tell You what's wrong & what's right, just advised You to keep conversation in private chat & respect owners of this forum =)
if You're rendering someOne else files for money on Your hardware with Your licence - that's a service (in my eyes =)
