With xpra, you should be able to get less than 0.5 sec, network
permitting. (and not with IE...)

Xpra can transcode to most of these formats in under 0.1s, other more
efficient formats like opus and vorbis take even less time.

WAV or MP3 can get decent results, the ultimate goal is to use AAC in an
mpeg4 container. We're not going to mux it with the video because that's
just too messy (there can be no video at times, etc...)

I am working on the HTML5 client updates right now, just bear with me..
