Yes, there is some work being done to use Spread as the group
communication system
for Postgres-R, but we are just getting started with this software.
Using a group
communication system to establish total order messages is one of the
basic principles for
synchronous multi-master replication with Postgres-R. Currently
Ensemble (form Cornell
University) is used, but Spread looks to be more robust and it appears
to be supported
on most if not all of the PostgreSQL supported platforms.

It's very cool to see positive testimony for Spread, and I hope I will
feel the same way
as I become more familiar with it.
