I see a lot of talk of VPN's here and the attempts to incorporate it into tomato. I have never set-up or used a VPN and I am wondering what sorts of interesting things can be done with it. I am just an average home user and don't really have a "business" or work reason to have a VPN. So I am wondering, what benefits can a VPN provide to a home user? I hear that gamers use it for remote LAN's. Other than that I can't think of a good reason to set one up (I'm not saying there aren't any, I am just wondering).
