Right, and since that sentiment is shared by the human hosts of
millions of Internet hosts, we have to make sure that our standards
allow for it. Of course, there will be situations where local laws
don't grant a right to privacy, but we need to be sure that IETF standards
allow for the preservation of privacy. That has been established as a
pretty strong consensus in the IETF a number of times.
