[RTW] [dispatch] Fwd: New Version Notification for draft-alvestrand-dispatch-rtcweb-protocols-00

[David Singer]

I have to agree.  If IPR issues are what we want to avoid, VP8 seems like a poor choice (e.g. <http://www.digitaltrends.com/computing/mpeg-la-looking-at-patents-for-googles-vp8webm-video/>).

My understanding is that the IPR situation wrt. VP8 is still unclear and thus risky. The other issue with VP8 is, as far as I know, the lack of a clear spec out of which independent interoperable implementations can be created.
