I use D-STAR Digital Data on 1.2 GHz for my Winlink RMS Packet CMS 
connection, 24/7.
The Pactor 3 mode that I use for Winlink HF forwarding is proprietary.  
But nobody else has come up with anything near as good (yet).  So a lot 
of hams use it because it does the job well.
We use D-STAR DD 1.2 GHz as a backup to the local internet connection 
for EMCOMM at the EOC and I do the same at home, too. WebEOC for example.
D-STAR is another tool in the box, another readily available method that 
might be better in a particular circumstance.  Why limit myself by not 
having a set of metric sockets for my wrench?

But to the subject how about some D-STAR DD on the satellites?  You 
would need to figure out a way around the L-band downlink e.g. a receive 
converter from another band or something...
Maybe not necessarily (easily) feasible but nonetheless perhaps a 
thought path to other digital ideas for satellites.  Both data and voice.
These are just more fun things to think about!

By the way, did you know that the MCU on the Fox-1 satellite is 
proprietary? ;-)
