I have been involved in a testing run with this technology a few years back.
We set ut a 'server' that constantly transmits an idle signal. when a station recives this idle signal it establishes an 2 way comunication with the server on 2 frequencies. The link lasts for only a very short time.
Messages between stations are always sent via the 'server' making it possible to reatch half the continent with one server.
It's not so easy to eavsdrop on this system, you can easily find the idle signal, but unless you'r located very near one of the comunication stations you won't be able to eavsdrop on the databursts. This happens becouse the ionized atmosphere only creates a very limited footprint (area where you can hear the other station)
we devised our own simple protocols for the testing. We did not use IP becouse you have very short time to transmit, and in that time you need to do handshaking and conduct as much datatransfer as possible.
My experience is that the system is very stable, reliable and secure. Pity you can't get very high transferrates.

Way easiest is to use an amiga.
since the amiga can read and write both pc and mac
disks.
