From a business perspective, what is to stop a
site from sucking in
just enough to mirror in real-time, and then turning around
and
forwarding it to other mirrors? In an extreme case, there would be
only one customer of this service (paying say $1000) and they in turn
might have multiple customers of their own (say 11m paying say $100);
the original customer will turn a profit just from reselling the feed,
the secondary customers will save major amounts of money, and all
benefitting from advertising. I doubt we could prohibit it
contractually, and even if we could, suing fly-by-night outfits would
be tough, even in addition to the PR aspects.
Even if we couldn't contractually prohibit this, we could just turn off the
feed.
