Forgot to add that I've unofficially started a little web-app for controlling my mp3's. Currently called 'mp3pad', it serves up a php-scripted page that shows all my mp3's and allows for playlist functionality (rudimentary currently). My setup is a server upstairs, 100' of speaker wire to downstairs stereo (ugh!) and mp3pad calling madplay for low cpu usage (and fidelity!).
Originally created it as 5 files with frames but went frameless (and 1 file, gotta love php) for dillo/iPAQ functionality (nought like walking around wireless and playing mp3's on stereo with ipaq as the interface).
Pondering allowing access to others (maybe allow a sub-playlist for external choices) so my stereo can be another 'internet device' for ppl to globally toy with... would be interesting.
