I just went through your previous post "No Consensus at IETF" where you kind of answer my question and explain why Cisco supports H.264 over VP8. I watched the whole recording of your presentation, it was really good. Of all the reasons you state, I think the most critical one is the first one : The huge H.264 installed base. And the other reasons also make sense, but should improve over time as VP8 use would grow. Still I think that pushing for the standardization of a royalty-needing codec is not a good thing in the end. MPEG-LA should free H.264 like Google did with VP8
