I came across a company called InterTrust that claims to have developed a
system whereby digital content can be downloaded to a user's PC, the user
be required to pay for 'rights' to use the content under certain 'rules'
set by the content provider and yet the user will somehow be prevented
from copying, duplicating or distributing the content. This system is
supposed to work offline.
Somehow I don't see how InterTrust can prevent a user from copying the
state of his PC prior to his 'using' the content, then use the content and
then restoring the state each time he wants to use the content.
Theoretically the user could distribute the 'state' of his PC to others
and circumvent InterTrust's protection scheme.
InterTrust's system is explained at

I'd be interested in a critique of this scheme.
