I admit my eyes glazed over half way through, but this[1] seems to suggest their "transcopyright" system incorporates permissions and micropayment systems.
Yeah, they've got a whole complicated permissions scheme that, to the best of my knowledge, does not and has never fully existed.
The parts of Xanadu that do exist seem to be mostly "goodfaithware," if you'll excuse the term. It's not clear that they have any real protections (like DRM) against clients copying data and/or not obeying the unique addressing scheme.
