Is this issue resolved in the law? Is possession of an
encrypted copy less of a violation of copyright law than
possession of unencrypted copy? Would these servers even want
to have a large amount of encrypted data that would be used
by a relatively small number of users? I think I have not
been following this list long enough, as it seemed to me that
the general www goal was to make the maximum amount of information
available to the maximum number of people. If that is the case
is use of the system to distribute materials meant to have a
limited circulation even wise? There will never be just ONE
information network, in any event.

That will almost certainly be the case.

It might; on the other hand, what difference does it make
if the illegal copy was made on a computer instead of a xerox
machine. If you have unlicensed software running on your machine
and the software police come and find it, can you get out of it
by saying you didn't know it was there? (I don't know the
answers to those questions, but these matters are not so different
and courts have been deciding them one way or another...)
