If we use UIDIGI set to WIDE2-2,WIDE2-1,WIDE3-2,WIDE3-1 , we've used up all four
slots. Fine, but what about support for RELAY? The hierarchy has always been
that low stations respond to one alias (relay) and higher stations respond to
the lower aliases and additional aliases. Do we run RELAY as MYALIAS? We'll
run into dupe problems, but it'll work...
I just read http://www.ew.usna.edu/~bruninga/aprs/kpc3+WIDEnCUT.txt and it shows
UIDIGI ON RELAY,WIDE2-2,WIDE2-1,WIDE3-3 , so looks like you forfeited WIDE3-2 in
lieu of RELAY.

I'm glad NOID will go away... I've wanted to develop some sort of intelligent
routing scheme, but without the digi's not knowing their neighbors, it was
impossible. One of the problems with TheNET routing was the tables getting
transmitted every 10 minutes got in the way of traffic. If we can trace each
packet, the digipeaters can passively learn their neighbors w/o any additional
network load. And, yes I recongnize that some RF links are asymetric.
