I think you would propably be able to establish that with the following:

Amavisd-new:    an smtp proxy for spam and virii
postfix:        anyway, propably anything compatible with Amavisd-new will
do
nportredird:    or similar, a proxy featuring load balancing, maybe just
iptables

MTA receives the email as usual. It passes the mail to filter (amavisd-new)
via
smtp call. Put here theport redirector proxy or iptables rule, so that the
call
is redirected to some of the cluster. Mail will be scanned thru, and fet
back to
MTA for final delivery.

No hard to do, and the result would be just what you need. spamd would
propably be unnecessary, as afaik amavisd-new do it's part: it is resident,
and loads spamassassin code with it.

How's that?
