In fact, if I use autossh to create the link, it will automatically reconnect after suspending my laptop for the night.

In a vaguely unrelated note I have users who have shell access to my machine despite all they need it for is uploading files to their websites via scp. It would be nice to be able to lock them down a bit more. Thanks for the brevity tip ;-) That does work although I’m sure there is a way to restrict actions to specific keys rather than users.

I've not tried it though. I would guess you'd need the -N option to ssh when the shell is /bin/true. One very minor change to your shell loop to make it smaller: while :; do ssh backchannel; done I think you can have ssh connect as a user with /bin/true as his shell. I’ve not tried it though.
