Reading, But No Copying

[David Macy-Beckwith]

O.K., folks, here's the situation:

Unix Flavor: SunOS 3.5

Requirement: 

Create a file which is readable (by vi, more, whatever) by 
common-or-garden users BUT NOT COPYABLE. We need to let them examine, even print, the info, but not jury-rig some results by copying, 
editing, and printing the file.

Comments:
It would seem that read-only for the world/universe/others
(004) would do the trick, but no, vi will read that puppy in and then
let you copy it to your $HOME with no problems.

I suspect I am missing some concept in the realm of Unix file 
permissions (wouldn't be the first time). 

Please e-mail me, as I am able to check my mail much more frequently
than I'm able to read Dah Net.

Thanks in advance.
