Using a GPS coordinate set as keying material? Hope it's just
additional keying material. Knowing the intended destination of
something like a movie in transit to a theater seems pretty easy,
and the set of GPS coordinates encompassing your average
multiplex would seem to be pretty small compared to the usual
keyspaces discussed here.
