I remember seeing a thread on the coda lists (which has the same hard 
linking between directories problem) that had a mail server working on 
coda that used procmail as the MDA, and that used the rename() call 
instead of hard linking the files so it worked without modifications.

BTW, why can't AFS allow hard links within a single volume?  Doesn't the 
client know where separate volumes are mounted in the /afs tree?
