Yes, Rev's script protection does not attempt to hinder any form of
alteration of the message path, it merely prevents scripts from being
read. If you could copy an object from a protected stack to an
unprotected one, its scripts would become exposed.
There is a request to support password-protection of any object, not
(Note to RunRev: I am not soliciting votes here, just noting an existing
report that is relevant to the conversation. Whether or not someone
decides to add their votes for it is entirely at their own discretion.

If you're copying objects, you may find it both more secure and more
convenient to maintain to have as few handlers as possible in those
objects, which merely call handlers in a central library or your app's
mainstack to do the real work, e.g:
-- In copied object:
-- In some central location:
-- all the cool stuff your object does
-- goes here
Not only does this provide complete protection for your proprietary
algorithms, but it also makes the code lighter in the copied objects,
minimally reducing memory usage. But more useful is that it keeps the
complex stuff in one place, so it can be maintained and enhanced without
needing to make sure that all copies of the script are kept in synch.
Just curious: What options does Toolbook provide for script protection?
