On a side note, megabit speeds on HAMNET? Holy Crap. Most packet radio only talks maybe 9600 baud max. Hmm. Come to think of it, Linux does have kernel-level AX.25 networking support... Anybody up for Quake over radio? :-P
Other than that, it'd be pretty cool to see that.
I kind of wish that weren't the case. At a minimum the protocol should be documented and unencumbered by patents.
