Looks perfect to me. If you can convince your clients to run qmail and
have qmail-qmtpd running, you could even deliver to them with
maildirqmtp (sp?).

qmail never touches anything in cur; just tmp and new. MUAs should be
the only thing moving files from new to cur, and you won't have an MUA
looking into your spool maildirs.

Hashing is your friend on slow filesystems. You'll also want to use
morercpthosts.cdb for related reasons.

As far as qmail is concerned, the message has been delivered (it's no
longer in the qmail queue). But if your clients' primary MX is down for
a week, they've got bigger problems, and you'll probably have been
contacted by them in that period.
