i think the idea of getting at the various devices these things export would be great. this was part of the GSoC proposal for getting drawterm on the iPhone/iPod Touch. doing it for android would be just as neat (especially personally, since Verizon has said they're getting android phones soon). in either case, it should be possible to do the export in the "proper" environment without too much hassle. for android, i'd start by figuring out which of the java styx libraries use the subset closest to what android offers.
The java subset is fairly large. I havent tried the existing styx libs much except to check out that the com.vitanuova.styx client code works (I dont think it supports server stuff though). I have my own server 9p code right now so it would be fairly easy for me to export a simple device like gps or the accelerometer in pure java. Drawterm would be a lot more work. ps: running native C code on the existing phones is fairly easy to do, although its probably not "really" android and may not be guaranteed to work on future phones.
