One thing that I do not see mentioned here is multicast. Are there any advantages? Watching a live sports game, for instance. Since multicast is connection-less and sent only over UDP, the more distant discussion about introducing multicast into browsers never takes place. Having used a multicast video stream for many years in an enterprise setting I can unequivocally state that this would decrease network utilization. Especially in the years to come as the interwebs get clogged up with broadcast-type data.

The main goal of this effort is to explore server-client communication scenarios.

ISPs are not supporting multicast over the public internet.

[RajuVarghese]

They will if it becomes a standard way of broadcasting. They will save quite a bit of network load.

The tech has been standardized as IPTV, and it sees a fair bit of use. But not over the public internet (for one, because ISPs don't support it...)
