AppleShare version 2.0.1 DOES HAVE a way to fully copy-protect files (both
documents and applications).  The administrator has to display the info
window of the file you want locked, check "Locked" and "Copy-Protected" 
boxes there, and then save changes.  

You're really combining two features, the ability to lock a file or folder
and the ability to copy-protect a file.  You can, of course, still make the
folder accessable to only a certain groups of users.

Combine these two features and you can have applications set at what we could
call "execute only."  A user can circumvent copy-protection for a document
by opening it and then saving it under a different name.

Note again that the copy-protection feature is part of AppleShare File Server
version 2.0.1.  This can not be done in version 1.0.  We use the newer
version here, and having the execute-only mode is nice.

See pages 150 and 151 of the Administrator's Guide that comes with 2.0.1.
