title: WP7: Store data in users live account
body: <p>For storing WP7-app-data it would be great if it was possible to use the current users live account. Is this possible somehow? I guess not. The alternative is for me to setup my own server to store the data, which means I also will have to implement account-management and require the user to create a new login and password for my particular app/site. This is not very practical as the user already has a live account on the phone. A compromise would be if I could use the logged in live-account on the phone as some kind of token to validate that the logged in user is who he/she pretends to be, and then store the data on my website.
