[quote=spdrun]Or just get a router that allows uploading an audited OS. Open source. dd-wrt or similar.
Not that what they’re describing is terribly practical outside of a lab.[/quote]
All I can say is that it does work outside of the lab environment.. so does radar. You can also send data on radar signals (by modulating the signal as if it were a standard carrier).
PS: many routers can be ‘rooted’ and there are open source executables and source code available for them. The more ‘clever’ routers with electronic antenna pointing are not all represented on the open source list though. It is kind of hard to get the manufacturers to be open on their interfaces to certain parts.
