Adobe Flash in a race against Silverlight for the most DRM

Largely by virtue of its support from YouTube, which some say supplies four-fifths of the Web's streaming video, Adobe Flash is the de facto delivery standard for video through Web pages.

While content creators have been urging Google and other video hosts to implement better controls over how unauthorized content can become so freely distributed, Adobe is now working on a way to enable those creators to post or host their own Flash video, in a way that they and only they are in control of the distribution process -- including, who gets to see those videos and for how much.
