Hi, it's not easy, but if you take great precaution and have a thorough understanding of replication you will be able to pull it off. Have you considered a master <-> master (dual master) replication setup? It's covered in the High Performance MySQL book by Derek Balling and Jeremy Zawodny: http://dev.mysql.com/books/hpmysql-excerpts/ch07.html However, be very careful if you have any AUTO_INCREMENT fields.
