  As I understand it, he's not looking to execute *any* command (even
a shell) on the remote (home, in this case).  He's just looking to
establish a long-term SSH session from work to home, so that he can
later use it to tunnel SSH-over-SSH, from home back to work.

  What he may want to do is create convenience entires in
$HOME/.ssh/config for each of these connections.  For example, on his
work computer, he might have an entry like:

	Host backdoor
	HostName foo.syslang.net
	User steveo
	BatchMode yes
	ExitOnForwardFailure yes
	PasswordAuthentication no
	RemoteForward 2222 localhost:22

And then, on his home computer, he could do this:

	Host work
	HostName localhost
	Port 2222
	User sorr

  End result being, he can run "ssh -f -N backdoor &" on his work PC
to get thing started, and then run "ssh work" at home to make use of
the backdoor tunnel.

  See ssh_config(1) for an explanation of the config file directives.
