Looking for a Mapping plugin - anyone find one?

Hey everyone,

I'm looking for a mapping PLUGIN for MU. I want to have a section in the dashboard for people to enter their domain if they'd like and map it to their blog.

I've see a few posts on it, and one on doing it manually with a LOT of steps (VERY well written though), but would like to have the blog publishers be able to do it on the fly as they would like.

Anyone find anything like this?
