A few days ago I loaded an install disk for Ubuntu into my Macbook Pro.  I booted up from the DVD drive and it loaded in beautifully.  I thought that I might back up the drive and run bootcamp to create a dual boot machine.  Then I heard that the bootcamp beta license will expire as of 10.5 being released...in just a couple of days.  Presumably a new non-beta version of bootcamp will be included in 10.5...so I will wait.

Today I received an email from the Joost Team to join the beta. They have created an OSX client but it has to be operated on an Intel based Mac.

Joost promises a combination of the TV experience and social networking. For example, live chat is available while you watch the content. It apparently uses a peer to peer scheme to stream content directly over a broadband connection using H.264.MPEG-4 AVC.

Installing the application was a snap. It was a quick download. It unzipped quickly. I pulled it into the Applications folder. Clicked twice on it and it launched immediately.
