[LAU] Linux Based Guitar fx / midi controller

I've seen talk on the list before of people throwing around the idea of a linux based guitar, but haven't heard mention of a linux based stompbox controller. I just ordered what I think will make the perfect stompbox case from http://www.surplussales.com/Cab-RacksHardware/encl_2.html, they have a 12" x 24" keyboard enclosure with a slant on it, which is very similar to the shape of a standard fully featured fx petal. my plans are to put a x86 based board in it that'll easily handle jack, rakarrak, sooperlooper, and some ladspa effects. build midi in/through/out ports in to it and a 16 char lcd, some stompbox functions that'll be mapped to midi commands. i'll probably build a 15" lcd into a portable case I have so I can track loop status of sooperloop easily, maybe even go with a touchscreen. I also use a roland gr-20 guitar synth, which is midi equiped. Just throwing this out for feedback for now, I hope to hear of some other people that have done similar things. wirelessdreamer
