Somehow, I cringe at the thought of a digipeater modifying the path of an
incoming packet, especially in the direction of extending it, even one
more hop. Not only will it increase channel congestion, but it also hides
obsolete or mis-configured TNCs, removing the incentive for an operator to
learn current best practices.
DANGER: You're on a slippery slope here.
That said, I'm of the opinion that APRS messaging as currently implemented
is a horribly inefficient protocol, and I would welcome a digi option that
will simply refuse to retransmit any message packet that has already been
digi'd ONCE, no matter what path the originator is requesting.
