Could you do it with unicast any better? I would say that regardless of the -cast, you would have to have accurate timing at all the receivers, and buffer ever so slightly to keep stuff in sync. Does MPEG have a standard for that - ie. "play this keyframe at time x" metadata? or is there some other way it's done? -- Nathan Ward
