A couple of us here in Australia have been kicking around the idea of a cheap network, running via repeaters in _very_ small boxes tossed all around a city, which would be indestructible through sheer numbers (a la the arpanet). So: anyone got any ideas, schematics, information?
The main idea is a huge number of small, low-power and CHEAP nodes which would handle through traffic which anyone with a radio modem could tap into, with the nodes disguised and placed in extremely hard to get to places (tops of telephone poles, buildings, on bridges and overpasses, etc).
Well, building the transmitter wouldn't be too hard, and you could probably transmit much larger amounts of data than over a modem if you used high frequencies. The most difficult thing as I see it is that you'd have to build a small computer for each box, and program it to route data packets, error-check them, and so on.
The idea being that we would have an untraceable, unbreakable network. Sure, you may have an address (perhaps we could set it up as a FQDN domain?), but that address would not correspond to any actual physical location. And, it would be free, aside from the cost of the equipment. No more phone calls to pay for!
A Fully-Qualified-Domain-Name type of network would create complications. Since the network will be constantly expanding and changing, you'd probably need relative domain names. (you'd have to specify: send packet thru site #10 thru site #34 and deliver to site #19) To have fully qualified domain names, you'd need to have something on the net cataloging them.
