Effective signing of everything you create would require supporting PC hardware, software, network equipment and whatnot. Also, such a solution could not be allowed to work on or with legacy hardware, because that would be a security hole, that means not transferring from "safe" PC's to "unsafe" ones.

How realistic is it to assume that ALL MAJOR VENDORS would manage to agree on something that big, when you can't even get two companies to agree on a next gen DVD format, and what is the chance of getting basically all major businesses that use PC's to completeley rebuild their IT infrastructure? The recording/movie industry is powerful, and they have a lot of money, but some companies are more powerful have more money.

And then, if someone found a hole after everything was changed over, everyone would have to start over again.
