Mobile music on demand using the modem port

Here's an idea I'm not going to implement, but liked enough to write down in my notebook 3 months ago: DRM-free music on demand using the modem port on your computer (that you're not using and will never use again). The idea is simple: control iTunes with a web browser and dial your mobile phone with your unused modem port, then--rather than connecting as a modem--you just play music over the line. In other words, use your mobile phone to play music, but rather than trying to do it as a data feed, you use the phone's audio capabilities.

Here are the elements:

1. A computer with audio out and a modem port, running a Web server; say, a Mac running OSX
2. iTunes
3. A script to control iTunes over the Web
4. The Mac2Tel circuit
5. A script to dial using the modem

The idea, if I was going to implement it, would be to build the circuit, then combine the last script with the first script to dial my mobile phone number from a home machine and start playing whatever music I've selected over the phone line. The Internet serves as the control channel, while the POTS is the primary audio service.

And, yeah, it's a total hack, but--hey--the elements are all there and I'm leaving it up the reader to put them together. (see "the devil is in the details" for more info on how to do that ;-)
