Shim-aware transports/applications could also emit periodic keepalives when they're otherwise idle so the shim knows it shouldn't remove state yet. (In fact many applications and/or TCP already do so.)
That is typically done as a hack to keep NAT-boxen from ditching you right?
No, I think it's done (at the tcp level) to flush out dead sessions. I rather like being able to put my laptop to sleep overnight and find my SSH sessions still alive, though.
Perhaps we are getting off topic but are you sure that isn't ssh doing the work for you? Ssh definitely has a configuration option for keepalive.
