Lets hope the people who engineer and launch such a system understand 
the difference between a decent social ragchew with a few pictures 
exchanged, and a DX contact - specifically the difference of about 50uV 
in signal level.

A lot of groundstation work needs to be done in the 1.3 - 10GHz 
microwave bands with regard to automated antenna and doppler tracking, 
and then the time will be right for 200uV+ megabit links and fully solid 
wideband audio.
