Joost's new CEO Michelangelo Volpi had this to say, "Joost is a piece of software and it can reside on a variety of platforms… It could be on a television set-top box. Or potentially it could be embedded in a TV set with an Ethernet connection, or on a mobile phone, or in some alternative device that might come out in the future."
Joost might have some issues however. They will have to compete with Akimbo and Slingbox which have been offering video content to televisions for years. Joost however, is free unlike those competitors. Joost's biggest problem will most definitely be getting the large TV manufacturers to include the software with their TVs which will certainly not happen without an extensive revenue-sharing deal.
More updates as they become available.
