I'm not sure if anyone has found this use for their IA-1, but here goes:
A couple of years ago a co-worker happened upon some old hardware. Among the mess was an IA-1, which I promptly started to work on hacking. I installed Midori on it successfully, and once the novelty of it wore off, I stuck the thing in the closet.
I happened upon a piece of open-source software called Slimserver (http://www.slimdevices.com). It is a streaming music server designed for their hardware, Squeezebox, but the software is just a server, so it works with basically any system.
Here's how I have it set up: I installed the server on my main workstation. The IA-1 is set up in the living room, attached to my stereo via patch cord (and networked to my workstation). Configuration is as simple as pointing XMMS to http://domainname:xxxx (where domainname=your ip and xxxx = port number--which you can set) and pointing Opera (or whatever browser you uze) to http://domainname:9000. You control everything from the browser window. You can configure a variety of options on the server here. The player view shows song and artist infomration, and supports album cover info as well.
It works great! And it gives me a very good use for the IA-1.
