An experienced reverse-engineer will gladly accept that challenge.
In this case it's easy - randomly hack VP6 codec and declare it to be
able to play VP8. I'm pretty sure On2 did the same.

Also I predict that RV5 and RV6 will be based on early drafts of H.265
and will have 1/5pel and 1/6pel MC correspondingly.
