Wine 0.9.11 runs µTorrent flawlessly (official Slackware 10.2 package). Right down to the tetris. Incidentally, it may be worth trying a winelib-compiled version of µTorrent - then Linux users can have a native executable without any code changes. (At least, that's what I remember of winelib, there may be some minor changes required). PS: Whoot for µTorrent and its awesomeness.
