Well, if anyone is interested, I can do a talk on emulator development, interfacing with various video/audio hardware and frameworks, and/or optimizing code for best performance (including ARM assembly and hardware considerations). None of these are Maemo-specific but they may be helpful to Maemo developers as well. Somebody has to be really interested though, as it makes no sense talking to an empty room. So, if you are interested, shout, and let me know what topic you would like best.
