I 've not heard of any. Perhaps there's a .moderated usenet group for it? All the movie discussion I typically partake in comes across through a mailing list specifically for people in the 3D industry (games, research, visual effects, etc), so most of the most of the conversation is FX related. We did get into an argument over the MR flailing arm GUI, though. There were a number of us who's first impression on seeing it was "overbudget Inferno* demo reel".


*Inferno is the most expensive compositing application one can purchase, due to it requiring the purchase of, at minimum, a 4 processor Onyx2 from SGI to run it on.
