I thought of a challenging undergraduate or masters research project this morning: an IRC logging bot or server add-on (aka plug-in) that intelligently transforms IRC content into threads. I may put up an example of what I mean if there's enough interest.
I also wanted to point you at my Mugar page again. It presents a new* multimedia gadget that integrates phone, mp3, radio, camera, PDA, web and email functions, along with (of course) voice recording and mp3/ogg/etc. encoding. There's an unbelievably funky user interface to go with it. Check it out!
