Rob, It is certainly analogous to the DRM access control interfaces, and I would expect that access to memory objects from the graphics stack would go through those interfaces (i.e. Xorg/EGL calls libdrm, calls DRM kernel ioctl, calls memory manger inside the kernel), but we need to make sure we have equivalent interfaces setup for non-graphics applications to make sure that all access control policy is honored. So, in short, yes, there's a connection :-).
