44.128/10 CANNOT talk to 44.0/10. 44.128/10 is, in their vision, a completely separate network, which can only be reached via RF. And to communicate with 44.128/10 you would need a new subnet within 44.128/10 ON TOP of your 44.0/10 subnet. So this makes routing in "home routers" (of which most ISP routers/modems cannot add any kind of static routes) more complex as you'll have 2 static routes to take care of and monitor.
This is the one part of the proposal I don't understand. Why not separate the two, but still allow those with BGP setups to announce any or all of 44.128/10 to the Internet, so that the RF network is globally routable, but without causing any probems for those with basic routers.
