Right. So Whether an Open Source CDM can be implemented is not a very
interesting question.

More interesting questions are:
Does Netflix plan to use the proposed feature only with CDMs that can
be implemented in Open Source software?
Do Microsoft and Google plan to only ship CDMs that can be implemented
in Open Source software?

(Where "implemented in Open Source software" means that the CDM is
implemented in software and is Open Source--not that an Open Source
browser calls into a non-Open Source black box.)
