Ansii, Louay,

- I agree that mesh (n:n) communication would complicate the spec.  Mesh communication could be better served by a separate web service that each presentation participant connects to, distinct from the communication channel offered by the spec.

- The scenario for 1:n communication between the presenting and controlling pages should be fleshed out.  There could be an explicit API to send a broadcast message, or we provide N different MessagePort-like objects that the presenting page could use to message to all or a subset of controlling pages.

Should the 1:n requirement be captured in a separate GH issue?

Yes let us file new issue for this req. maybe with the same priority as for issue #27?

> [Louay]  I share the same opinion.   I think 1:n communication (1 is presenting page and n for controller pages) is enough at this stage. n:n mesh communication will make the spec and implementation more complex. But If we find use cases where this kind of communication is required, we need to consider the n:n case. Currently I don’t have a use case in mind.

The generic n:n comms problem on the Web has not been addressed yet, and the still experimental BroadcastChannel only proposes a solution to same origin pages opened by the same user agent.

Thus it seems reasonable for the group to scope this API to 1:n communication (All - if you have concerns, please let us know).

Now, we'd need to tease out the requirements for the 1:n comms after which we can start to look at concrete spec changes.
