that is imho, a mysql-5.1 only feature, where you can have rbr and multimaster setups that actually work. and 5.1 isnt quite ready for release as yet :D

I'm running a multi-master setup with 5.0 in production with a moderate amount of success. I did try 5.1 a few months ago and it died a horrible, fiery death.

You will definitely need auto_increment_increment and auto_increment_offset and replicate-same-server-id set to 0.

FYI, I recently took a MySQL High Availability class, and multi-master is definitely not a standard configuration. It was only briefly touched on, and only one other person there had it running in production. But, while it's not officially supported they do their best to make it work.

Specifically, what makes you say it is a 5.1 only feature? What does 5.1 give you that makes it easier than 5.0?
