X server

Hi! I would like to run X-Window (set up on a server pc) from more remote machines for more users. (The users should log in from diskless computers. - this part is ok already) Could you advice me a good (detailed) description on how to do this? I know the diskless and root over NFS howtos, they're very good but don't say too much about setting up X this way. Should't I mount any directories for X? How is it working? Thank you.
