A full VPN could be useful to wrap Java Applets or custom browser extensions. I've found their support for proxy settings unreliable, especially if you don't want to leak info to the main network. (I ended up setting up a VM and routing everything through Tor, which worked but was complete overkill. It would be great if you could force an application (and all subprocess) to use a certain connection. Put a control in the titlebar/system menu that lets me select interfaces. Please, desktop developers, steal this idea!)
