[aprssig] Bob, Address the WIDE7-6 Possibility

Bob,
I don't think the new n-N Paradigm has been finalized (at least I hope
not).  There are still a BUNCH of problems that your plan does not
address.  You are under the assumption that people are rational and want
to play well with others; I have seen quite the opposite on numerous
occasions.  If you prevent the QRM, then there is none.  But with your
plan we are back at square one.  

Until we can get some REAL network control (i.e. hop counting in the
digipeaters) then I would refrain from using "finalized new n-N
paradigm" as I HOPE it isn't final!

73s,
Eric KF4OTN
