A precedence here is the recent font format discussions. Some parties
here wanted DRM technologies built in to the platform, whereas other
parties (mozilla and opera included) were pushing hard against any
technologies that contained DRM.

It's currently looking like a non-DRM based technology, WOFF, is the
one that will be the agreed on. WOFF instead allows ownership
information to be included in the font files so that if a copyright
breach happens, you can see this after the fact.

I would advice taking the same route with video. Allow *informative*
licensing information to be included in the video so that owners can
be traced or so that someone can automatically spider the web looking
for copyrighted content that has gone astray.

Of course, in order for this to work we need to all agree on a video
format, something that is currently looking unlikely to happen soon.
