I have no idea if the repo's that are in this are current for wine but the part to pay attention to is the registry entry.

Ubuntu Forums - World of Warcraft Howto

After you have made the reg mod by going to a gnome-terminal and typing regedit, I also created 9 copies of wow. 8 of which were "incomplete." Meaning I symlinked the "data", "interface", and "Accounts" folders back to the main unused wow folder.

Also one thing I learned is that using pip is necessary. It increases performance a lot. Having several clients open without them in "pip mode" slows the system down quite a bit.

Also I set <shift>-F1 thru <shift>-F8 to change which client is full screen. I also made 8 macro's that are controlled by the same <shift>-?? keys. This means when I change a client to main screen by typing <shift>-?? it also changes the leader of the group to that character. As well as changing "Grapevine" (addon it rocks) to forward tells to that char as well. It also changes focus of all characters to the main. This allows for universal macro that when clicked follows and assists focus. So basically I hit <shift>-F1 and 1 all characters change focus, follow, change leader and change "grapevine" settings. Making the need for one character to "lead" the others irrelevant. Any character can lead. Also if one dies simply press <shift>-F2 and your "second" client becomes leader simply press 1 and everyone will assist and follow.

If anyone wants macro's I use or keyclone.ini for 5 or 8 chars let me know, I'd be happy to help.
