What if rumors about Motorola's X phone offering customization are true? How do you think it'll be implemented?

There have been quite a few rumors about this, with Android and Me's sources saying it being worked on and Guy Kawasaki's controversial post about being able to customize a phone like a Porsche. So I was wondering how will they set us up to customize our phone? Can we order it from a b&m store(difficult) or online(of course)?
