Via Slashdot here is an article about broadband speed wireless. This is another component of my Streaming Internet Receiver thingy. Once there is broadband wireless as available as current cellular coverage I think there will be all kinds of interesting development on the client side for devices to take advantage of that speed.
In the article he mentions doing a variation of exactly what I want to do, “… I tested the reliability of the connection by tuning into a Web radio station’s 128-kbps music stream; over about four hours, I heard two or three dropouts.”
This is a very early version of media over wireless broadband. Someday, and it may not be that long, I will be able to use an iPod like device to select from a large store of all the music ever recorded and pick the piece I want to hear and have it start playing. It may be streamed or it may transfer the bits to my device first so I can play it from there but it will allow me to hear whatever I want where ever I am, for a reasonable price.
