Early theoretical work maybe, but there is still a strong interest in this
type of technology system. As I understand it, the InterTrust architecture
enables this as does the Xerox Digital Property Rights Language. However,
the question one has to ask is should we rely on such technological fixes
or should we have a system whereby we trust the original owners not to copy
and send to their friends? Many would say that a return to electronic
techno locks would be regressive and have the disadvantage of attracting
hackers.
