My understanding is that VP9 just wasn't suited for decoding using JS. The
demo Daala decoder offered performance similar to that of Route9.js, but it
is apparently still not optimized. Is it inherently easier to decode Daala
using JS/WebGL?  Do you think it will be good enough to make a material
impact on cross compatibility efforts?

Also, the Q/A section of every talk I've seen includes someone asking about
hardware implementations.  The response has generally been something along
the lines of "We are cognizant of the need for hardware implementations, we
are too busy to build one ourselves." – but this doesn't answer more
practical questions.

For example, how much do you think it will cost to add Daala support?  My
understanding was that since VP8/9 is very similar to h.264/5 it is very
cheap to add support.
