I don't think that requiring buffering is going to add much value.

Note that setting buffering to 5s means accepting an additional 5s delay between clicking on a link and getting any of the content, compared to the situation where negative values are not allowed. There are probably better ways to synchronise different media. -- Chris Lilley, W3C [ http://www.w3.org/ ] Graphics and Fonts Guy The World Wide Web Consortium http://www.w3.org/people/chris/ INRIA, Projet W3C chris@w3.org 2004 Rt des Lucioles / BP 93 +33 (0)4 93 65 79 87 06902 Sophia Antipolis Cedex, France
