At the end of the day, the video stream will be 'available' at some point and the industry has to deal with this and make plans on how to meet this otherwise they'll just end up in the same situation as the music industry. As some of you on this list know one of my companies is working with www.akimbo.com on distributing their vod network overseas, the content providers who have signed on with Akimbo (bbc, turner, A&E as well as the 400 minor providers) are taking a very realistic and proactive stance in the future of distributing their content on a global basis. For anyone to suggest this is going to go away is kidding themselves. Cheers, Dean
