I'm not a fan of D STAR but the protocol is very much open and Hams are 
building their own systems, just have a look at things like Dutch STAR.

Yes the codec is close licenced but everyone can buy the IC to decode 
and encode it for reasonable prices (between $20 and $30 depending on 
source).

There even people developing complete addons to do D STAR without a PC, 
just the addon and a 9K6 capable fm transiever.
