This looks like a really nice hack. I would love to install it but I forsee a problem with some of my users. Not that they are problem users. But once you change a username then everyone that knew you by your first user name will get confused because without warning you are not longer that name. Granted this should not be a problem and happen to often. But if you give everyone access to change their user names then this can encourage people to do it depending on who they want to be each day. I would like to install it this so I would not have to worry when someone who wants their user name changed. But I am afraid that other users will start changing their user name to often.
