The session stays alive as long as one of the machines does not get powered-off. I actually use tmux on top of a Mosh session with my laptop and the connection survives the IP address change from home to work (this includes the machine sleeping during transit).

The tmux/screen session is not required, but provides a good backup mechanism if your client loses power or otherwise kills the mosh-client process.

You might be interested in taking a look at the Mosh project (
http://mosh.mit.edu/). Essentially a UDP-based SSH client (and server)
with connection roaming and improved buffering.  It will require a
server component and access to UDP/6000x, so unfortunately not the best
of choices unless you own the servers.
Looks interesting.  Since it uses the connectionless UDP, I presume it
does not have the dropped connection problem that the standard, TCP
based ssh does.  Does it keep the [virtual?] connection nailed up even
across access network changes?  Does one still need to use, e.g.,
screen, to keep the session alive in such cases?

Thanks,
