Enter Joost (pronounced Juiced), a peer to peer (P2P) program for streaming video over the internet, developed by Niklas Zennström and Janus Friis, the guys who originally developed Skype. The development into an invitation only Beta has gone incredibly fast, as the real development of Joost only started last year. Some 150 people have been working on getting Joost to the stage it is today and it already works incredibly well. As a video on demand service it still lacks a few things, mostly a wider array of programs, as the content is quite limited, although it depends what you are looking for.
If you are lucky, you have already got Joost, or maybe one of your friends can send you an invite. If not, then you should ask if someone has it and if they can give you an invite, well, at least as long as you have a broadband connection, with unlimited bandwidth. The one downside of programs like Joost would be for those that have metered internet access , since it does eat up quite a few megabytes of your monthly allowance.
