Hey Dan,

Happy Holidays (god its boring to be PC)

In regards to this feature, how should this work with vpn's?  Here is an 
example:

- I'm connected to a wireless access point and I'm connected to the vpn 
as well.
- I have gaim connected to my irc sessions which are only available over 
the vpn...
- I lose my connection for whatever reason...
- I reconnect fine to the access point but of course the vpn doesn't 
come up automatically.
- before I get a chance to bring the vpn back up gaim is reconnecting my 
gtalk and other accounts, of course it can't connect to the irc sessions 
over the vpn since its not up yet..

My question is should gaim get another notification when the vpn is 
brought up.  and should it get a network going away before the vpn is 
brought up?

There are some things to consider too.  You might have your vpn 
configured to only route some traffic over it..  In that case it would 
be valid to not send a network going away signal before bringing the vpn up.

Thoughts?
