There would still have to be some type of frequency co-ordination
to prevent intermod interference to existing primary users of the
spectrum. Given that broadcast video is AM I don't think it would
take much power at the packet transmitter to screw up all the TV's
for several blocks around if you pick the "right" frequency.

Of course if you don't have any UHF TV stations around (like us) it
shouldn't be a problem...
