Ipaq music streaming

A couple of years ago I bought an Ipaq 3100 with a dud battery for £15 on eBay. My plan was to get it to do wireless music streaming so I could play music in another room without running cables from my computer.

Last night I finally got it working. I'm using esd and can play things from the computer, but I can't get esd with a remote server to work with mpd, my music player of choice. Will keep hacking on that.

Eventually I'd like to get it to work with a remote control, since it has serial on it. To test that out, I'll need a 9-pin null modem adapter. Anyone got one I can borrow?

When I get right into it, I might even end up with a user interface so I can see what track is playing. That would be cool.
