Hmm...mail servers. Easier still would probably be just to let the DNS
round-robin the (equal preference) MX records :-)
However, the idea of clustering with respect to synchronised data between
all the servers, rather than just distributing the data might prove useful -
if it was easy enough and transferable to unix (Solaris) systems then I'm
sure we would have a use for it :-) BTW, before anyone suggests just using
rsync, which we do, something a bit more 'zappy', and probably nearer the
network and protocol levels, is the way I would have thought it would go.
