I'm not saying you're a dufus. You could be connected, but not have your internet traffic being routed through my server.
It should be fairly reliable - Although it is a bit of an experiment at the moment. I'm planning on launching a service where people pay... $1 or $2 a month to access my VPN, and be able to have their browsing encrypted so that when using a public hotspot etc they are not made vulnerable. Also, since it's an American IP, people from outside the US can watch site's like Hulu, etc.
If it becomes popular, I might launch a UK Based VPN server.
