That part of the scenario is already covered by the above proposal.
(I admit that there are a lot of details I've waved my hands over, but
this would still work.)

I'm not sure how to handle that one.  How do we handle that today?

I'd call that a different channel, then.  I get NBC out of New York
and I also get NBC out of Philadelphia.  Only the New York channel is
WNBC.  NBC out of Philly is WCAU.  They're different channels with 98%
identical content.
