"Automatic" setting for bridge device

[Matthew]

The "Bridged Adapter" network setting requires that a specific network adapter be selected for a VM, and that adapter can't be changed without powering down the guest. For mobile users that frequently switch between wired and wireless network connections, this can be a problem.

It would be ideal if VirtualBox offered an Automatic setting which connected the guest's bridged network adapter to the host's physical interface using a set of rules such as the following:

1. If the guest's IP address (based on packet SRC?) matched a directly-connected subnet on the host, use the interface that connects to that subnet.
2. If the guest sends a DHCP request, route the request through the physical interface designated as the default route.
3. If the guest's IP address cannot be determined, or does not match any directly-connected subnets on the host, use the physical interface designated as the default route.

An Automatic setting of this variety would only work for TCP/IP-based networking, but that's perfectly fine for the majority of applications. In cases where Automatic could not be used, a specific physical interface could still be selected.

With VBox 3.1 it has been improved very much, and users can switch networks on the fly now.

Please look at it, and come back for comments.
