neteventd is supposed to be started by the user. There is currently
no hook to actually run that.

There is a program I was playing with called miid that will watch the
(physical) network and start/stop the network when it sees the link
arrive/go-away. Unfortunately on my particular laptop running miid
causes the USB controller to go into a weird state, but it still might
be an interesting thing to include if we're interested.
I do not know of an miid equivalent for wireless. It might be useful
to write a gnome applet that lets you see the current wireless config
and then turn the wireless device on/off. Unfortunately this would
also depend on the particular wireless driver being used.

I sent a patch to the openafs guys that should cause AFS to timeout
quickly in the event of no-network -- so that should at least cause
SOME of these hangs to mostly go away. My patch was just committed
to the OpenAFS HEAD last night.
In my experiments with running disconnected, AFS was the #1 delay, and
DNS/Hesiod lookups were #2.
