It's similar to NXDN in a lot of ways. 6.25kHz FDMA. In fact, as mentioned above, some Icom and Kenwood NXDN radios will run DPMR.
And, since it's got a wide acceptance amongst manufacturers in Europe, it would be something that could/should catch on here in the states with some users. Eventually getting forced to 6.25kHz channels is going to happen on the Part 90 side, and that also means that eventually amateur will go that way also. It'd be pretty dang awesome if amateur radio would chose a common digital standard shared amongst manufacturers. While DMR, NXDN, Fusion, D-Star, P25 are all nice, having a common very narrow band emission common across amateur radio would certainly benefit the emergency communications side of ham.
