 client needs 45Mbps pushed over 20 miles... and he wants it wireless. the
 kicker is that they don't want a T3 because it is "too expensive" and it
 would take too long to get installed. it doesn't need to be constant, but he
 wants to move of 2.5GB within 45 minutes. this is in the chicago area, if
 that helps any. so, i don't know, satellite?

802.11a might do what you need.  Not sure if it has been standardized
yet, but if not there are a number of proprietary implementations
in the same speed range.  It promises 50Mbps with similar properties
to 802.11b.
i read somewhere 802.11a was going to be like 50ft distance. you'll need lots of wireless bridges.

20 miles is going to be a long throw, but not outside the range of
possibilities if you have line of site and good rooftop acesss.  You
will need some big antennas though.  A site in the middle making it
2 10 meg shots would be ideal.
