anyone has experience with pgslq Cybercluster 2 ?

Hi there i just noticed announcement of cybercluster 2 release for postgres.

http://www.cybertec.at/en/postgresql_news

they say its open source but did not find downloads on their site ; )

Anyone has experinece with it? i loved postgres and used to work with it for
a long time but lack of easy and reliable replication forced me to move back
to mysql. To be honest did not look at postgres for a few years now  : /

Anyone could share some tips on php-pgsql-replication experiences?

cheers
