There are two discussions here: feeding information back to the
broadcasters from each viewer, and developing standards for receivers
which must interoperate compatibly with all broadcasters.
To feed back info to the broadcasters requires the separate two-way
link. End of story.
And for the CE industry to develop receivers that all broadcasters can
benefit from, as opposed to designing specialty STBs for each
broadcaster, would require the sort of collaboration among broadcasters
that we have not often witnessed.

So, you really think that each of the local broadcasters will be
developing their own STBs. Great idea. And you really expect people to
buy 6, 7, or more STBs to be able to benefit from these new services.
Brilliant. Any other flashes of genius?
As to how many services can be multicast over the same 20 Mb/s broadcast
channel, fewer words and more simple arithmetic are in order. Just add
up the bit rates.
