Same here, way too much email :)
I've been good - only 412 unread out of 40,033 in my INBOX. (And yes,
I can open that fine on my 770 over GPRS).

So that no packets are sent or received on that interface. But IIRC,
we ignore DHCP packets but any other IP packet is tracked.
Okay, so it's tracking interface level activity?

It closes the connection. But that's use configurable, it can be set
from the Connectivity Control Panel applet.
Shuts down the association or the physical interface? (And I know,
I've suddenly switched to OSI-speak to avoid the word "connection"
here)
And is this done merely if associations are idle, or only if there
are no current associations?
It makes a huge difference to the viability of the 770 or N800 as a
platform for mobile email, and I'd have thought it'd degrade the user
experience for XMPP as well. Take a look at the highly readable
http://www.ietf.org/internet-drafts/draft-ietf-lemonade-deployments-04.txt
for some general guidance for the mobile email case.
