It's theoretically possible to write software to automatically compensate for the doppler, and pipe the downlink to a server.  

If someone out there has the time, I could explain how to do the tracking, doppler, and talk to the D7.  

Right now, I'm working full time, and attempting 6 semester hours of graduate coursework in math (real theorem-and-proof math).  

It seems like half of each pass is lost if you use a fixed doppler shift.
