> When software implemented by anyone can't be what acquires the keys, the next best solution for achieving platform independence seems to be defining a virtual machine that can be implemented by anyone as a white-box environment for executing a program that's so obscure that it's effectively a black box, so that the providers of such obscure programs would only need to target the virtual-machine platform instead of having to target every non-virtual platform. In the context of the Web Platform, a Web Worker executing JavaScript is the natural answer for an execution environment.

How would this enforce restrictions on the use of the decoded media?

If the 'virtual machine'  can be implemented by anyone then how can restrictions on the use of the outputs of the box be enforced?
