I've been using this addon, only problem is still having to edit the savedvariables with new toon name and copy the file over to the other WTF directories, but it saves the hassle of having to setup the actionbars on all your toons. If this thing eventually gets some sort of broadcasting to other toons (or similiar feature integrated into Jamba - hint hint)... It'd be pure gold.
