permissions

I want to set up a server with a lot of users so that (in order of importance):

Users cannot obtain ip addresses of other users with who, or last
Users cannot wall
Users can write to each other
Users are able to selectively mesg n other users, as opposed to simply blocking everyone

Point 1 is easily solved by a 660 on wtmp and utmp, but I don't know how to achieve the other points

The server runs Gentoo Linux
