What about DRM/ERM that uses TPM? With TPM the content is pretty much

Will ERM/DRM be ineffective even with the use of TPM?
ERM/DRM/TPM are such poorly defined and implemented products that people have
started referring to a "DRM fairy" who people assume will wave her wand and
solve whatever problem is at hand. I used to try to draw out the mentioner's
claims into a concrete proposal that everyone could objectively examine, but
the conversation rarely progressed that far. So now I think that, as with
other crypto proposals, the onus should now be on the proposer to clearly
delineate what they're proposing and convince us that it's complete and
correct, rather than us nodding our heads or lashing out at what we assume it
means.
So I guess the answer to your question is "We'd better assume that DRM+TPM
will be ineffective until we've subjected a specific implementation of it to
the same level of scrutiny we apply to other cryptosystems, and since DRM+TPM
proposals tend to be much more complicated than other cryptosystems like SSL,
that's going to take a very long time."
