[Xastir] IGATE

[Gerry Creager]

What Bob wants is doable, and I've posted info on how, a couple of 
times, in a conceptual manner.  Now I (or someone competent) needs to 
commit it to code.

What we need, however, to do it properly is a new network paradigm that 
allows this at the APRS equivalent of Layer 3, in each major metor igate.

The major problem with the method proposed here is scalability. Neither 
the APRS-IS nor the current code base can expand to accomplish what's 
suggested.  The fix must be more fundamental.

Academically yours,
gerry
