I think it is a great idea in theory, the execution is difficult. I was thinking more along the lines of using a personal domain that would be hosted by web hosting company. It would be really an encrypted set of files or database that could be queries like a web service. The owner would have to register or allow different services like Home Outlook, Work Outlok your PDA, etc. to sync up with the list. This encrypted block of data could also be used to store files and host your email.
