The discussion I've seen surrounding the issue is mostly centered around the user (browser) and video quality. The thing that most stuck out to me from the post, buried in the end, was the (potential) restrictions that could be placed on creating h.264 content and publishing it on the web. I think that this is the biggest relevant issue I've seen yet with h.264. Apparently these issues are still potential and still under wraps, but I would not be in favor of effective restrictions on including the <video> tag in a website.
