Can you clarify what your actual motivations are here? any user can only affect their own files and such, so whatever they can do they can only do to themselves. If you mean with regards to doing cp on system wide commands, then you can use the sudo framework to allow certain users to do very specific things as root and nothing else.

I agree with Chris, please clarify why that would be desirable!

Yes, it's possible. Instead of bash, give that user a "shell" that only understands "mv" and "cp" (note that they won't be able to log off). You could write that as a perl script. Yes, I've done it and it works; my script understood only "exit".

Beware that the user could effectively remove files even if you don't allow "rm". E.g.:
Code:
mv file-a /tmp/.gone
mv file-b /tmp/.gone
cp /dev/null /tmp/.gone
