Stefan,
It appears that stations attempting to work D-Star via satellite would need to use two radios. This was the case a few years ago, when AA4RC and N3UC were able to make a brief QSO on AO-27. You can read about what gear the used, along with some useful tips for trying D-Star via satellite, at:
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.
