Hah, yea, that's likely the case globally. More curious though for cases such as particularly problematic regimes. I know at least for awhile, FIDONet was a way that information flowed across firewalls because firewalls blocked TCP/IP traffic, but of course didn't filter traffic flowing directly over phone lines. Obviously radio has its own hazards as anyone who's ever done a fox hunt knows that locating the transmitter (or at least the antenna) is pretty trivial with a modest amount of equipment. But the optionality so that people can do their own risk assessment and decision making around it would be cool to see.
