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.
