[This comment does not address the merits or otherwise of using NFS for
this purpose.]
Sharing the spool directory is not currently possible if multiple hosts
are putting messages onto it, because of the small but finite chance of
name clashes. I did design a scheme for using one or two of the high
base-62 digits in the second part of the name (currently the process id)
as a "host identifier", to solve this problem, but haven't yet done
anything about it, though it wouldn't be a lot of work.

Neither am I! I'd have to look at it.
