Which websites will live stream the Beijing Olympics opening ceremony?

In half an hour, the opening ceremony of the 29th Beijing Olympic Games in 2008 will begin. I believe that many friends in the IT industry are like me, without a TV in our residence or office, and thus unable to watch the live broadcast on TV.

We can only watch the Olympic opening ceremony through the internet.

Everyone knows that some P2P network TV platforms (such as PPlive, PPStream, TVRen, QQLive) will have live broadcasts. However, these softwares are not installed on my computer, and I don't want to download them just for temporarily watching the opening ceremony.
