How would the usage model of the TPM shared by multiple namespaces look
like? What subset of functionality is available to each namespace and what
works and what doesn't? Again, how is the sharing of PCRs accomplished?
I think we should treat this sharing of the hardware TPM discussion
orthogonal to the vTPM so that we don't get hung up with it.
