Ah sorry, you are right.  In that sentence I meant
a "higher hop count"...

1)  But that is adding 7 bytes 100% to all packets from
that tracker and already packets from trackers are
the highest number of packets we are burdened with
already.  Thats a big load for little value *most* of the time.

2) We already have most of the DIGI pre-emption 
capability at any existing digi that is supporting the 
New-N Paradigm.  It is the TRAP function.  If a 
fixed rate 3-3 blathering tracker enters an area
that is only 1 hop from an IGate, that digi can have
3-3 in its TRAP list and the packet will be digipeated
once, callsign substituted and it WILL get to the igate
and no farther.

THat pretty much does pretty good now.
