Proxy Servers

In order to view Hulu shows outside of USA, all you need is a VPN (Virtual Private Network) service. With VPN, your computer will be connected and assigned a new USA IP address. Therefore with the new IP address, it is possible to view all Hulu shows or access any services that are limited for USA residents. Hotspot Shield is a free VPN service software.
It allows a 3GB traffic limit a month for free and more traffic can be purchased (Only works on windows)

Tor: An anonymous Internet communication system

Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you anonymize web browsing and publishing, instant messaging, IRC, SSH, and other applications that use the TCP protocol. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features.
