Wes, 
I completely agree.  If I use all of those in my UIDIGI setting, then that leaves no room for the weather LANs that I have been implementing.

The weather LANs look like "WXMHX" and allow I-Gates to send weather bulletins to RF and keep them within a specific area of interest and no further.

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.
