@Kry:
Do you know the current status of wxCocoa? (IIRC, you're also involved with the wxWidgets developement, otherwise just forget about this question)
Just because i recently managed to get amule compile with wxCocoa, but it looked like shit (it wasn't usable) - and i wondered if thats because of amule (which was optimized for wxMac/wxCarbon, but probably could be tweaked for cocoa as well), or wxWidgets (which couldn't really be fixed in a decent amount of time)
