well my main issues with ip is the pre-setup overhead needed for a "cb" like setup.

as in, you have to make sure everyone is on the same subnet with their own address...

and without a central server, like what dhcp uses, this can be a issue if all you want to do is turn on the radio, send some data, and turn off again.

still, now that i think about it, there was some kind of protocol developed for doing this, server-less. maybe baked into zeroconf, maybe not. could be interesting to look into.

btw, ad-hoc still needs one device to be a "master" device in the setup, no?

ok, i guess we could always bump all devices into "promiscuous" mode or something to get the desired effect
