Thanks Bob... your message summarises exactly what I was just about to say
so I won't re-type it!

I have some other comments for some previous post when I get time (Cycle 2
of Chemo starts today!)

At the digis, yes, but to the users, it is just an option
depending on their immediate comunications requirement.

I think what he means is that it should be implemented at the
digipeaters so that it is available for those who need it or
want to participate in a "regional" net or event without QRMing
surrounding areas too.  The classic example is someone who lives
on the far edge of a "state" and wants to send his APRS traffic
to a state net.  But it takes him 5 hops to hit all the
participants in that state net.  ("Net" here is a special say,
one-hour net for a stated purpose of limited duration and
participants)...  If he used WIDE5-5, he would saturate all
surrounding digipeaters in all directions out 5 hops hitting
maybe 50 digis.  But if he used STATE5-5, then his packets would
only go to the few digis in his state and no farther.

For border areas that want routine all direction operation, they
simply continue to use WIDEn-N.  But the border folks have the
added option of targeting a give direction too, which can only
be seen as an advantage...

Just 2 cents worth.
