I was brainstorming a bit about this the other day as well, but I don't have the time/resources to do anything with it. Why can't we have a digital identity that isn't attached to a particular service? If I want to change cell providers I can take my phone number with me, but if I want to switch ISPs/Email providers I have to get a new email address. It would be useful (and in the interest of competition) to provide a way to contact your identity, and you can configure your identity to dispatch messages to whatever service you happen to use at that given time (somewhat ala Google Voice maybe?)
