Method to allow users ability to have two easily switchable usernames ?

[rnmcd]

Is there a way someone could devise a method for users that have multiple usernames to easily switch between them?

Is that something like you see done on a SMF mboard? There you have your normal name and if you want to go by something else, there's a blank where you could put a different name as a handle.

No, I was looking for a way for my users to have 2 different usersnames (where each one could have it's one profile) and, most importantly, be able to switch between them quickly....
