If the signature in the content prevents it from being played,
it can be considered a technological protection measure that
restricts the rights to the work, and violates teh anti-TPM license.

Dave would have to send a clear copy of the work to Alice,
and then some sort of DRM-er that adds the signature to the
work that Alice can run on her side.

anti-TPM does not prevent this. But parallel distribution doesn't
either, and parallel distribution allows other monopolies that
anti-TPM prevents.

As for Alice applying DRM to the work on her local copy,
I equate that with Dave sending Alice a proprietary binary
library, some GNU-GPL source code, adn a make file
that builds the two together. This has been allowed in GPL
for a long time, and I see no reason it would be a problem
if it were allowed with DRM.

To prevent it would require preventing Alice from applying
DRM to her local copy, and that seems a step too far.
