I see what you're getting at - the user owns the data and access permissions (stored on the web), and the services work from that. With S3, this is a much more realistic idea. The problem is that many services will not allow your information out, such as facebook. The question is, is this something alot of people want? I know what I would like is to be able to always export my data out into a common format (like xml) so I can use it somewhere else. If there were big demand for this kind of service, a startup could launch that became MyWebApps.com - a place where your data is stored and which has interfaces to the key other apps that you use and allow data to come out and possibly synchronizes etc. Your portal to the web where you always go first. This is a pretty ambitious idea with countless lines of code involved for getting all the different systems to speak the same language, but if it were pulled off, it could be big.
