Hmmmm. Ok well, thanks for the input. Do you know of any decent replication
services then so I can use a satalite server farm?

Postgres doesn't care, although a lot of the oldtimers here will tell
you not to use NFS for any data you care about.  Check the archives

Multi CPUs in an SMP box is fine, but not independent systems.
