Nothing leaps to my mind at this stage, beyond the flexibilities we discussed yesterday and you already seem to have those in your plan. Besides external services that aren't "AG-aware" but "AG-useful", I'd also add capability-matching that is done by the client, and perhaps done dynamically/real-time (based on information from the venue server perhaps) - so for example the ability to use layered-video-codecs on different multicast addresses to deal with bandwidth constraints. I can imagine defining and advertising my node's ability to send such layered encodings to the venue, but each receiving venue would make it's own decision on what to accept based on local circumstances (which may change over time - my downlink might congest suddenly and temporarily). This doesn't require capability-matching in the literal sense, so I don't know if it impacts what you're trying to do and I'm just talking for the sake of talking :-) or if it's a different aspect of the same problem, i.e. !
wher
e do capability-matching decisions occur, centrally or locally - or both? That in turn probably depends on what the transports and encodings let you do.

Cheers,
