Definitely cool. However, one thing users should beware of is that file locking doesn't work all that great over NFS. Even sendmail and pine users are cautioned about using an NFS directory for the mail spool because locking is not guranteed to work. I have found that having hypermail archives processed by a seperate computer (along with other jobs that do various web site updates) using NFS for access to hypermail files is very useful because it puts less load on the web server.

This is likewise just FYI.
