+1 - it's by no means my preferred solution, but it's one I can live

with, and better than the alternative of the status-quo - no MTI at all.  If it wasn't for OpenH264, my answer would be different.

I can't see adopting H.264 as sole MTI, and I can't see that we'd get consensus to adopt VP8 as sole MTI.  That basically leaves stone knives and bear skins (aka H.261) just to claim we have MTI, nothing (wild west), or this.  (Unless magically MPEG-LA changes their mind - in which case that might trigger the kickout here.)
