Does anyone actually have that (any node
can go down and the others still replicate amongst themselves?)

you are describing usenet. (it was not designed for relational database
replication but it does have that feature)

  Reliability, Availability and Scalability
Mirroring the data on multiple nodes enhances reliability of the database system. As Postgres-R is using a group communication system it is easily possible to add or remove nodes on the running system. Crashing nodes are automatically detected and removed, thus do not affect the operating of the database system. This facilitates administration tasks and ensures greater availability and scalability of the database system.

I think some disclosure is in order about postgres-r:

"Please note that this is *experimental* software. primarily released for review by developers familiar with Postgres."

Looks interesting though...

Gerry
