Here's a straw-man:

* 5 storage nodes
* 2 proxy servers

5 storage nodes for a reasonable zone breakdown for 3 replicas; separate
proxy nodes for security segregation (working to avoid unencrypted,
unauthenticated rsync having any chance of leaking through the net) and
network segregation (separating replication traffic); and at 2 proxies
for HA.

I'm interested in hearing about both private and public cluster sizes that are deployed for production use.  4 nodes or fewer doesn't  seems pretty small - 6 or 8 seems like a more realistic size of a small cluster. But I don't have any actual data/customer experience for those assumptions.
