I would have to disagree there. While there will sometimes be WIDE1-1
fill-in digs in the valley, you can't count on them being there. If the
high WIDEn-N digis didn't also respond to WIDE1-1 and the mobile station
didn't happen to hit a fill-in digi, it wouldn't go anywhere. If the
WIDE1-1 digi and the WIDEn-N digi both fire off at exactly the same
time, no harm is done.

Why not just install the IRLP APRS status script? It will generate an
object for the node on the fly that will tell others the frequency, the 
status (idle, connected to, disabled etc.) and then get the local IGate 
to gate it to RF... preferably direct or via one hop if it's appropriate 
for that area. It would really depend on the kind of coverage the IGate 
itself has. I would tend to reserve digi-generated repeater objects to 
regular repeaters that aren't capable of beaconing their actual status.

It can be difficult! Just use WIDE1-1,WIDE2-1 wherever you go. It will
work most places. If you happen to be in an area where digis are still
using obsolete settings, too bad. They will (hopefully) one day be
updated, or they will just die and be replaced by digis with up-to-date
settings. Of course, you don't have to wait for them to die. Just put in
an appropriately located fully-compliant WIDEn-N digi and use that
instead of the obsolete digi.

Keep on encouraging! Be diplomatic. Try and encourage new people to get
into APRS... for the right reasons. Use the recommended settings even if
you are surrounded by obsolete digis. It will take time, but we are
getting there. It's all downhill once we get to the other side!
