A facility for musicians to virtually jam on the Intnernet.  “Licks with Friends” or the like.

Not sure where things are at with the platform this would require, but I think we’re probably still a ways.

What’s the latency below which you are all playing in rhythm?  Actually, half that latency I guess, since I have to react to your cue and play something back.  That’s what we would need.

Plus it would be a nice-to-have to see the rest of the group as we play, although I’d settle for audio-only in R1.
