I am testing bucardo (http://www.bucardo.org) in star replication with
one office at Canada and 3 branches in different countries and it's
working really nice. It's not yet in production, but my test show that
it's really good for star replication as you need.
BTW, my replication is bi-directional and all the branches syncronized
with the others.
