If the systems are in the same location and can use a shared Filesystem then I would look into getting a netraid scsi card or something similar. The netraid cards have the very nice capability of all sitting on a single scsi bus along with the datastore device (a hard drive or hdd array). There's no replication that occurs because they are all using the same data source jointly.

The application for which I have an immediate requirement actually uses
postgres *and* files. the files are required because of stupid
external reasons, they are collected and FTP'd to another system beyond
our control. I'm already intending to evaluate Slony-I for the
postgres replication.
