As for D-Star being developed specifically for amateur radio, from

digital technologies foramateur radio 
<http://en.wikipedia.org/wiki/Amateur_radio>. While there are other 
digital on-air technologies being used by amateurs that have come from 
other services, D-Star is one of the first on-air andpacket 
<http://en.wikipedia.org/wiki/Packet_%28information_technology%29>-based 
standards to be widely deployed and sold by a major radio manufacturer 
that is designed specifically for amateur service use.<<<
