This would be the "killer protocol" for the freedombox, if combined with some smart dyndns management.

Here is a use case scenario I am imagining. I define two servers for myself: home.me.com and cloud.me.com. Where home.me.com is a dyndns to the freedombox. Dyndyns being unreliable, if a tent msg cannot get to my home server, then the messages are sent to cloud.me.com and then pushed to home.me.com when it comes back online (think POP mail).

The facebook killer then, is a hosted service like cloud.me.com for non-tech people, but a seamless transition to the hosted at home service as soon as you buy a freedombox. This way you have the best of both worlds. Your face in the cloud, and long term storage at home.
