If this were similar to SGX (which is what I initially assumed) then "not yet" is a perfectly reasonable position to take. However it's actually homomorphic encryption implemented in hardware thus not relevant to DRM (AFAIK). That said, the unfortunate reality is that the same constructs that underpin DRM are also required to build a secure system. The only difference is who controls the root of trust. As such the problems with DRM (and hardware ownership more generally) are political as opposed to technical in nature.
