[aprssig] Universal digi path

I'm not aware of a "user-initiated" Gate-to-RF mechanism, and I somehow
doubt that exists.  However, if you know an IGate operator in your home
area, you can make a special request to have him/her specifically gate your
traveller call back to RF.
I do this fairly regularly when there's a SAR exercise that puts some of the
teams out of reach of "central control" (some of these exercises are way out
there). They'll set up a temporary IGate where they are (sometimes using
dial-up), and send me a list of callsigns involved. I'll gate them back to
RF for the duration of the exercise, and the central control station is
direct from me.

The key is that you need to find one of the local IGate owners in your area
who is willing (and able, some gates are 1-way) to set it up for you.

This raises an intesting point - as I understand it, if you want to track
one station (the traveller) from another (home) that are more than a hop or
two apart, you have two choices:

1. Use a long path that generates QRM over a wide radius, or

2. Use a short path to reach an Igate from the "traveller", then track the
traveller from "home" via the internet.

If you don't have access to the internet from "home", for whatever reason,
option 2 doesn't work.

Is there an existing path mechanism that would route data over the air from
a "traveller" to a nearby Igate, then back to the airwaves from a specific
Igate close to "home".

Perhaps something like W1-1, W1-2, [home Igate callsign]?

This would use the internet like a wormhole to get the data off the air
where it isn't needed, but put it back on the air in a specific region. This
way the only packets that would be on the air would be those right around
the "traveller" and those close enough to "home" to be monitored.

Just my ramblings...
