hmmmm... there *might* be a way. But most of the existing ways I just googled were flash base, so...
I'm pretty sure someone will come out with a way. I know there are a few guys working on an easy way to get your iTunes Library streaming to you via a web browser. It will be interesting to see what they are able to come up with. (I know you can stream iTunes at the moment, say, from a home computer to a work computer, but I don't know if iPhone will handle it)
