Has anyone ever received film festival permission from Blizzard?

A quick question for the assembled masses - has anyone ever corresponded with Blizzard via their [email protected] address, and if so, what was their response? In particular, has anyone received permission to embark on commercial activity with WoW, or to enter or show Machinima made with WoW at a film festival?

We’re about to do a roundup of Machinima licensing in 2009, and I’d be really interested to know how responsive they were.
