I'm not sure that's true anymore. Specifically, I know that Linux's 
NAT implementation, which accounts for several of the common DSL 
routers, doesn't timeout a silent connection until a matter of days.

It might be interesting to talk to the NAT implementors, and see what 
timeouts they're actually using these days.
