Yea, I live in a rural area, and do SAR in even more rural areas, so
I have a strong need for extra "help" up to the mountaintops.

If we used "myalias wide1-1" on the house digi's, and set our mobile
paths to "wide1-1,wide2-2", that would help.

If we tweaked the client software so that it would have a small dupe
queue, delay digi'ing a bit and then check whether a packet had
already been digi'd before trying to digi it themselves, it would
improve the network a lot.  Xastir has a similar scheme for igating
packets to RF, but not for digipeating.  It could be added, or we
could rely on digi_ned for that sort of functionality.
