any video without ads is currently left out of the html5 beta. It will be interesting to see if they can find a way to have ads work with the video tag.... whether it is through a change in the nature of the ads or a technical solution.

Overlays (eg. ads) are not exactly a problem to insert onto html5 video via canvas and/or svg. Probably easier to filter on the browser end, though, as the ads would be inserted by the browser itself and not a third-party binary blob interpreting another.
Generally, forcing something using open technologies doesn't work for savvy circumventers; I don't think that's a major problem for the ad business though since most people don't bother to block ads anyway.

It would not be too terribly difficult to do. The trick really just lies in how the server integrates with the ad display, which can be as simple as streaming an ad without seek support before the video itself, or as complex as using AJAX calls regarding ad display time, mouse behaviour, and clicks back to the server for usage pattern verification before streaming videos. Truly savvy users could get around having to see the ads but not get around necessary pauses and wait time before the video plays, which pretty much negates any reason to block the ads in the first place.

I was surprised a few months ago when someone mentioned ads overlayed on youtube videos; it turned out I have blocked *.doubleclick.net in my dns and that stops youtube ads completely. Hopefully this will still work with html5 ;).
