http://easy-vpn.comodo.com/ Comodo EasyVPN allows businesses and home users to quickly group multiple computers into a secure, peer to peer, network over the Internet. EasyVPN requires no expert configuration, is fast and easy to set up and uses 128 bit encryption to recreate a cabled local area network over the Internet.
So maybe if you and I and a couple of other freaks wanted to trade some porn over the internet, privately, this may be the way to go?
It also requires trust in the company you select. But after all the Wifi issues lately, the more the merrier I guess.
