If caller-id is enabled on your line (i.e., you paid ThePhoneCo to turn
it on for you), you'll hear 202 modem tones at 1200 bps between the
first and second rings.  Methinks you could hack up an old 202 modem to
deliver this information to your computer.  What's in there is the
digits of the caller's phone number and a few flag characters.

I'm waiting until Telebit or one of the other advanced modem
manufacturers offers this in their standard product - i.e., the modem
loads a string register with the contents of the CLID on an incoming
call.
