The AUTO thing with preemption fixes that.  No need to run AUTO if you don't
want to, and if it's not fully implemented yet, you just run WIDE2-2,AUTO.
Say I put a digi up on Plowshare peak to serve the local area here - you
transmit with WIDE2-2,AUTO and it gets rewritten as WIDE2*,K6SYV-10 and goes
only one further hop, but hits at least two Igates.  Out in the desert,
maybe AUTO gets rewritten as WIDE3-3, or CA3-3, or whatever.

Hmm, that brings up another question - does preemption need to set SSIDs to
0, or is it sufficient to set the H bit?
