Sounds interesting... would this be the new officially supported method 
for sharing mailboxes in all cases? Or is this just for shared mailboxes 
on NFS shares?

It sounds like this might be a proper (fully supported without kludges) 
way to get what I had asked about before, with respect to expanding on 
the concept of Master users for sharing an entire account with one or 
more other users...
