Well, in lieu of anyone else clamoring for a spot, here's a couple of ideas:
1. I've spent a good amount of effort and thought on improving the performance of Wine's synchronization primitives. It's a difficult problem, and one I'd like to bring to Wineconf, informally if nothing else. I could give a presentation on this. It'd be probably very technical. I haven't written anything yet, but 15-20 minutes of talk is probably not unreasonable.
2. I could give an update on Wine-Staging. I'm a little hesitant to do this because, unlike last year, I don't think there's necessarily very much to talk about. Still, if anyone wants to hear an update, please let me know, and I'll see what I can dredge up.
ἔρρωσθε, Zeb
