Re: [gentoo-user] How would I disable Flash (oand other things) for a single account?
Probably it's not the best solution (and it's easily revertable), but you may try disabling Javascript in Firefox (or whatever browser your user will use). Another solution (but I don't think it will work) is to chmod /opt/netscape/plugins/libflashplayer.so to -rwxr-x--- (0750) and then change it's ownerships to root:video (or another group you may want to create).

If so, I think you can use NoScript/FlashBlock to block that kind of stuff with success. If you don't want someone to play video, you'll not only need to block the browser plugins, but any software on the company capable of playing video (such as mplayer, xine, etc). Massimo's suggestion of altering the file modes to remove read access from that user sounds good. Maybe it would be easier with ACLs so you can specifically deny that one user access. But I've never used ACLs so I can't say for sure it would be easier. :)

What happens after an emerge that updates the files? I have to go back in and change owner:group on the files again? I'm sure you're right and this is probably the right way to do it. Thanks, Mark

ACLS maybe? I've read about it but never had a need to do so.
