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:
The 5 kHz tuning steps for D-Star radios would make satellite operating difficult as you mentioned. AO-27 was the ideal satellite for this sort of experiment, since its uplink receiver was intended for use with data, and doesn't filter the lower end of the audio range that it hears. Plus the control operators of AO-27 have stated clearly that they support and encourage D-Star on AO-27, something not seen for any of our other satellites.
From a quick read of the IC-9100 instruction manual, it
is clear that D-Star was not intended to be used in this radio for satellite operating or for anything other than the "normal" D-Star operations (RX and TX in the same band, simplex or repeater). You could use the IC-9100 as one of the two radios for D-Star satellite operation as those guys did for AO-27 a few years ago, but you would not have access to the IC-9100 satellite functionality.
73!

D Star satellite?
That sounds like a need idea. Would be nice to do some tests on existing satellites.
With SO-50 it will not work unless someone has figured out how to have D Star (DV) active on any D-Star radio with the required tone enabled. Won't work with the IC-9100. Tried it. Another problem is the 5KHz spacing since you pretty much have to be right on the frequency on the TX and RX. Also, on the IC-9100 it seems to be not possible to set D-Star (DV) on the RX and TX in satellite mode. Anyone else tried it? Also, SatP32 has at the moment no DV functionality for the IC-9100. I guess we have a long way to go :-)
