I think this post got quite "unnoticed" due to throwing too much mushrooms in one soup - not rightly though, as some ideas here are quite nice (yet, rather for different projects).

Could you, please, write more about, how - from hardware side - things like:

[quote]easy audio I/O data app using ax25, fax, or psk31 so off network data becomes possible using CB,PMR,FRS,MURS, amateur radio, amateur satellite, shortwave, marine radio, and business radio; preferably using the easy share with a service so that anyone can use a FM radio to send a picture or file even if the local phone cells are shut down.[/code]

...could be possible? Using FAX & friends protocol sounds very interesting (would allow to send thingies without actual network connection, just using voice dial), but sadly, I don't know about anything about pre-requiments.

OTOH, other ideas - like amateur radio and FM - I can't imagine how we want to achieve it on N900 hardware-wise? Not saying that it is impossible, but it would help to write more about practical implementation ideas.

// Edit

Speaking about independent ways of communication, it's pity, that mesh network never worked OK in our case, and was cut from kernel-power (IIRC), instead of getting fixed
