Interesting. I spent the last week writing something quite similar using
paramiko (a python ssh library).
The ssh protocol is quite interesting. You open a transport channel, and
the you can open random control channels through that transport, which
are much like sockets. paramiko includes support for executing commands
down via the transport channel, as well as opening shells.
You can see my random sample code here:
Anyways, I don't think this fixes your problem (the judicious use of
ssh-agent, and some sort of monitoring to yell at you when it goes down
seems like the solution to that), but I'm getting really into this whole
ssh as transport thing.
