Reconnect possibilities (was Re: telnet and SIGHUP)

[Bob Rasmussen]

This topic brings to mind an idea I have kicked around for some time.
Suppose I have telnetted or SSH'd into a Linux/Unix server over a wireless
access point from my laptop. I move around the office complex, and lose my
connection.

At some point later I link up with a new WAP, maybe get a new IP address,
and then connect back in to the same server. What I WANT is to be able to
reconnect to my previous session, which has been carefully suspended at
the point of the disconnect. Of course, authentication would have to take
place.

I believe I could create a protocol for doing this, and modify the SSHD
program from, say, OpenSSH.

Does anyone know another, existing approach?
