        In the ham radio community for several years there have been
devices called Gunnplexers available (I don't know if that's a brand
name or a generic name) which are a 10 GHz microwave system for about
$200. When they first showed up there were several articles in ham
radio magazines descibing how to send video through them, so 10 Mb/sec
is probably not too far out of line. Except for maybe the feedhorn
(or the dish itself) it would easily fit into a briefcase. The range
is limited but I think to line of sight rather than 1 mile.
