hi !

I thought about some other possibilities:

1) interfacing a microcontroller through ethernet.
I found a very cheap java controller with ethernet + 2 serial ports for 50$ (http://www.ibutton.com/TINI/hardware/index.html)

2) custom interface on the IDE-channel (very interesting for the mk1 owners :)

I only heard about one project, which uses the IDE-interface (somebdy build a SPDIF out on the IDE interface).
But maybe our IDE-guru knows more about this ?
mlord ?
