Well that's good news. I understand that just because Mozilla decided it 
was OK doesn't give me any cover, but Tim is certainly in a better 
position than me to make that decision since A) Tim actually understands 
how the codec works and B) has a legal team to get approval from. It 
also occurs to me that, irrespective of the IETF, Xiph itself would 
probably not adopt opus if they thought it was encumbered.
