I need to be able to lock files at three different levels: - protect

(essentially make it so that only some people can open the file as
read-only, and the rest can't open it)
Why are you asking individual documents to do what basic network
security and permissions is designed to do? You can accomplish
everything you describe fairly simply on any NT-based network by putting
documents into appropriate network folders and setting permissions.

You could set up user groups with the type of permissions you describe
and give those users access to folders on the network. Is this not an
option? Of course, I am assuming that you are talking about a network in
the first place.

Ken's suggestion works well for your first scenario. For the second and
third options, save the file in a "read-only" format such as PDF and
still use the OS security features to control access to the files.
I put read-only in quotes because even PDF files can be altered, just
not so easily. PDF files can also be password protected to add an
additional layer.
Finally, there is the extreme: Put the entire network inside a locked
area - that means no connections to anything outside the room(s), deny
to everyone the right to carry any media in or out (Yes, with briefcase
/ body searches) and put the entrance under the control of a security
guard. It's all a matter of how serious you need to be to protect the
data in your files.
