>They rue the day they decided to just let the microwave ovens have 2.4 GHz, because now that frequency is proof that there is no physical reason to "license" electromagnetic radiation.

What do you mean by this? 2.4ghz is used for low-power, short range communication, so of course there are fewer issues with interference. You can't say the same about the FM radio bands, for example.

See sibling note by 'rayiner. FM as broadcast now is really old tech. Car radios would have to be updated to have cognitive radio capability, if this regulatory regime were extended to that band. But that doesn't have to happen soon; the spectrum is vast and could certainly accommodate more unlicensed use without inconveniencing this particular use.

EDIT: In case this is still unclear: I'm talking about opening specific, limited bands of spectrum to unlicensed use. I would not nominate FM radio as the first such band. Just as wifi chips today are capable of not interfering on bands they don't use, super-wifi transmitters would not interfere on bands they don't use.
