Interesting concept of GEO and LEO integration. http://www.space.com/35801-satellite-data-relay-service-exit

For what it is worth, APRS is doing something somewhat similar (but the reverse) on Ham radio (and of course, free)....

We have a Ham APRS channel on 3 GEO Inmarsat birds giving us outbound delivery everywhere on Earth with a simple raspberry pi receiver (except upper alaska) Then we use the 3 APRS LEO satellites to give the return channel to any ham anwyere on earth with his APRS handheld radio.

A neat system, ... though, looking for an application .... as usuall ;-)
