I'd suggest you take a look at the Linux Journal Article that was
referenced earlier in the thread. My friend Dan got a nice piece in
their on his D-RATS software which does short messaging over a HAM
network (don't butcher me on correctness, that's about the extent to
which I understand it).
http://www.d-rats.com/ - His Project
http://www.linuxjournal.com/issue/189 - The Linux Journal from Jan 2010
dedicated to HAM stuff
http://www.linuxjournal.com/magazine/amateur-radio-survival-guide-linux-users?page=0,0
- his article that covers a lot of the basics, including the D-STAR
network, which sounds exactly like what you are describing.

Wow great find! Uber-cool stuff.
But, microwave is Line-of-Site and don't think it can be deployed in an
emergency situation.
Thus I was thinking a lower frequency one that anyone can purchase ( as
in License and money ) and deploy with lower power need (thinking solar
etc ) thus GMRS radios at UHF 462.550MHz to 467.725MHz so with a
repeater can go up to around 20 miles.
Best would be 2 meters with repeaters (144.000 Mhz to 148.000 MHz) But
back down to 1200Bps or less.
With good repeater maybe 100 miles over flat land. Then down to super
slow SSB and AM with 27Mhz ( old CD radio ) but really long distances
and no longer line of site.
But then I'm thinking the info passed is "tweeat" like very short
messages like "120 casualties at location gps coordinates ..."
Not talking about downloading all 1.2 Teri-bites of star trek.

Folks a lot brighter than the lot of us here have done everything you're
thinking about, plus a bunch more:

http://hsmm-mesh.org/
There are many good reasons that's not happening with VHF / UHF radios,
though, not the least of which is bandwidth.
