[aprssig] Bob, Address the WIDE7-6 Possibility

Then as a general rule, an N digi that has good coverage should not respond
to RELAY, right?  RELAY should be used very sparingly and then only at
smaller "home" sites.

If we leave RELAY as an alias on the big digi's, the bad apples will soon
figure out they can do RELAY,RELAY,RELAY, right?  Then we are back with the
same problems.

I say kill RELAY entirely.  It can be just as bad as WIDE.  Let's just move
on with WIDEN-N and SSN-N and the advantages of the dupe checking that they
bring.

RELAY will still be supported.  Just discouraged because
they cause so many dupes.  If your area can handle all
the dupes and you want mobiles to keep using   RELAY
as a first hop, its up to you.  But I wouild suggest that
first people should try it without the initial RELAY and
make some statistical comparisons (including counting
all the dupes) before making up their minds.  Bob

Looks like this just put the HOME RELAYs out of work.  I disagree with
the 
percentages. What to do now?
