Methods for quickly/easily copying UI between characters?

[Neef]

I'm trying to get back into WoW, but one of the hurdles is setting up my UI between all of my characters. I'ma bit of an altoholic.

A lot of addons have profiles that help, but mileage varies between them and sometimes things don't copy perfectly between profiles.

Is there a technique I can use to copy exact settings and placements between a lot of characters?
