TouchTones(tm) are used all the time in satellite feeds to cue local
programming. If you get a satellite dish (one of the big ones) and download
directly (and you find an downlink that isn't encrypted these days) you
will hear them all the time. There are codes for "insert your commercial
here" and "breaking news story" etc. They cue automatic switchers at the
local end.

Somewhat apropos the recent thread about sending mains power
through modems, can anyone tell me if it's legal or illegal
here in the States to send data in the audio of television or
radio? Certainly there would be bandwidth and therefore speed
limitations, but does the FCC allow this? Is it legal in other
countries?
