If the new satellite has AFC and a 2m uplink, existing D-STAR radios 
should be suitable for the uplink.  That leaves the downlink, where I'd 
probably use something like an all mode radio with computer controlled 
Doppler correction and a GMSK modem with DV Dongle or DV-RPTR board with 
an on board AMBE decoder.

Where things could get really interesting is D-STAR allows easy 
interfacing to the Internet, so theoretically, you could enable (for a 
few minutes!) global connectivity to remote areas.
