I do 250 mbits on 21 transponders :)

Ok, while this is off-topic, let's just point people to Wikipedia:

Other satellites (which are NOT in the same position at all times from
the prospective of a spot on earth):

http://en.wikipedia.org/wiki/Geosynchronous_orbit 


TV, and other fixed positioned (relative to the earth are
geostationary):

http://en.wikipedia.org/wiki/Geostationary_orbit 



perhaps further comments can go to the discussion pages on Wikipedia
since I would wager a very small number of us push any serious number of
bits via satellite.

Geosynchronous are only over a particular longitude.  They move up and
down in latitude, so it isn't over a given point except twice per day
(or only once at the extremes).

I don't speak for anybody but myself - that's enough trouble.
