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.
