But what happens if some over-eager early adopter of long-field
callsigns (AX25 V3.0 ???) starts gating this stuff into the APRS IS.
Will the IS server software accept it? (As it accepts "bogus" SSIDs
above -15 now). Or will it choke? Or just ignore it?
Further, assuming the IS accepts them and passes them forward, what
happens when "AX25 V3.0" packets reach end-user client software logged
into the IS. Will clients ignore them or lockup in a cloud of buffer
overruns, parser errors, etc? Not to mention reverse-igating messages
to current AX25 2.2 users on RF.
