Is it okay to use BF read-only over NFS?

I'm in the process of consolidating and breaking apart functionality of
some of our mail servers and would like to move towards a system like
[ NFS ]
[ MAIL 1 ] [ MAIL 2 ]
Where the "MAIL" servers are qmail-ldap clusters that do SMTP / POP /
and IMAP. All mail and individual's .bogofilter/ directories will be
stored on the central NFS server.
This came up before:
And I would like to run by my setup by everyone:
1) incoming email is sent to the correct server and is run through a
dot qmail (like procmail) script that puts it in a folder if it is
| condtomaildir ./Maildir/.spam/ /usr/bin/bogofilter -c
/home/vmail/.bogofilter/bogofilter.cf -d ./.bogofilter
so this is *read only* access to the database file
2) mail that is incorrectly scored is moved into a make(good|spam)
folder. Every 30 minutes the *NFS server* goes through those folders
and does the appropriate -Ns or -Sn fix to the word list.
So at any given moment there can be N number of processes accessing a
user's wordlist.db in read only (-v) mode as mail can come in at any
time. At a timed interval only 1 process will update the user's
wordlist (-Ns or -Sn). I can't guarantee that during an update of the
wordlist an email will come in and try and do a -v on it.
Does this sound okay to everyone? I'm currently using 0.92.8 --
should I migrate to 0.93.5?
