I was thinking of that, but reading the encrypted media extension proposal, you don't have to include DRM to comply:
This specification does not define a content protection or Digital Rights Management system. Rather, it defines a common API that may be used to discover, select and interact with such systems as well as with simpler content encryption systems. Implementation of Digital Rights Management is not required for compliance with this specification: only the simple clear key system is required to be implemented as a common baseline.
I will wait until they make a move to actually mandate DRM be included in the standard.
I know that even having the ability to include it is not that good, but they will want it, so I don't think I can stop that.
