I think anything I touch becomes something noone else wants to work on :P. I expect though that I'm still allowed to work on anything that sparks interest or fix bugs that I find annoying. ;)
A brief list of some major things few or noone other than myself ever maintained since I got into it: * SWCODEC recording (mostly the middleware layer and codec aspect, not the screen itself) * threading (much to do here yet regarding proper mutex usage throughout rockbox, implementing dual core for real but for PP5020 problems) * threading/queueing aspects of the kernel * a good lump of DSP, especially the CF assembly sections * PCM buffer and PCM HAL (much waiting here but for PP5020 of course, auto core-selecting pcm playback, major HAL improvement in general and one I'd like in place before gigabeat S is on the list too) Really, as long as I am able to work on rockbox, I'm willing to maintain any of my own code I ever contribute or introduce via accepted patches. The goal is usually to introduce something in a form that requires little maintenence and is flexible enough to allow future ports to just "plug in" to it with little new work.
