John,
But you can do all of those things today with non-Icom projects. It
is a question of the G2 network at this point, there is a lot of
politics going on about who and what can connect, but the technology
exists.
One example - http://k7ve.org/site/index.php?option=com_content&task=view&id=33&Itemid=26
though I now have a GMSK board and am working on getting a real
repeater (probably Kenwood or Motorola used equipment) to hook it into.
SSB was patented at one point (1915 - see: http://en.wikipedia.org/wiki/Single-sideband_modulation)
. This "mode" / protocol is more open than many of the others were
initially, its a homebrewers world right now or you can buy from Icom
(which I will for handhelds and mobiles).

True, but perhaps those who could manufacture "D-STAR compliant" (or
perhaps just "DVAR") radios aren't motivated to do so if they can't
compete in and affect characteristics of the infrasturcture market -
repeaters, controllers, etc.? It's still not an open mode like the
others - AM, CW, SSB, FM, PSK, etc.
