I've updated http://wiki.winehq.org/SummerOfCode, but it's a bit short on project ideas. (Somewhat on purpose -- last year, people just copied and pasted our detailed project ideas. This year, lets give fewer details and more ideas... if somebody's really interested, they'll ask for details on wine-devel, and that process will generate fewer boilerplate applications.)
