You're missing the point.  Nobody has to force anybody to do anything
(except the FCC - hi) but monitoring your equipment makes you a responsible
operator.  I'm not talking about 24x7 monitoring and having a speaker on
your tracker.  That is silly.  I'm talking about just checking on things now
and then.  I thought this was common sense.  This includes IGates, Digi's,
trackers - any transmitter.  If you set up any transmitter and *never* spot
check it now and then to make sure it is operating properly, then that is
irresponsible.

You could and it wouldn't hurt a thing (other than findu).  Don't get
hung up on the AX.25 spec when it comes to APRS-IS.  We do not use AX.25
on APRS-IS.  We use text/binary strings that loosely follow the TNC-2
monitor mode format.  As Bob points out, that has always been assumed to
mean ANY 9 characters for a callsign-SSID.

Maybe so.  Guess we should also force trackers to have speakers in the
vehicles (and be visible) so the operator is a good "steward" of the
network and doesn't transmit too often or get stuck on or uses too long
of a path or etc. etc. etc.  Most of the APRS RF bandwidth is consumed
by these types of problems, not IGate operators "set it and forget it"
abilities.  Many IGates are similar to digipeaters: located in places
where "set it and" (more accurately) don't change it is not only
desirable but necessary.
