Automatically connect to vpn

[Harald Solheim <harald solheim chem uit no>]

When at the University I need to use VPN to get internet access. When I
am at home or at other locations I need to use VPN for access to email
and scientific journals, so I use a different VPN profile for this. I
have seen that NetworkManager can run a script when there is a change in
network status. Is there any way I can have NetworkManager automatically
connect to a specific VPN profile depending on which network I am
connected to, and get  the normal visual feedback from nm-applet about
the VPN connection? I sometimes lose the VPN connection, so it's nice to
get a notification of this.
