C/R demo for Linux Plumbers

The linux Linux Plumbers will take place in about three weeks. I'm interested in preparing a nice demo working for the c/r presentation. Something visible.

For example, start a sort of a "session", checkpoint, reboot, and then restart the session. The session can be 'screen', or even 'sshd' (w/o persistent connections).

It's also an opportunity to boost development particularly of pieces necessary for such a demo :)

Ideas, comment and code are welcome.

Oren.
