I respectfully disagree. I'm sorry, perhaps the word 'poster' is misleading. In the HTML case, it is not an advertisement for a resource which is 'miles away', as a movie poster is (it's on a billboard, the movie is in a cinema), it's a proxy for the video before it's played in the same place. I think it conceptually wrong to have alternatives for proxies -- the proxy and the alternative are peers. On Dec 8, 2010, at 10:46 , Gregory J.
