Use a VPN connection and/or proxy setting automatically when connected to a certain network

Binary package hint: network-manager

Hi there!
This is actually a feature request.

The use case:
When I am at my university I need to use a given vpn network and proxy. I think many people are in a similar situation where they must use a given set of settings only when connected to a given network.

The idea:
The proxy settings allow the setup of "places" which are essentially a saved proxy setting one can easily switch to. This is a great feature which could also be implemented into Network Manager.

The proxy settings "places" should be extended to Network Manager and there include vpn connections. They should be tied to a set of network connections. So when I connect to a cetain LAN or WLAN (even automatically) Network Manager switches to the corresponding "place", so that my vpn connection and proxy settings are enabled automatically.

The gain:
Right now when I go to my university and power up the laptop, Network Manager automatically connects to the university's WLAN but I then have to enable the vpn and proxy settings manually. When later connecting to my home network, I have to change the proxy settings again. With my suggested feature that would all happen automatically.
