Do you mind if I clarify those requirements?

The two-way replication (Master<->Master) replication is  
asynchronous, so you need to try and prevent updating the same row on  
both nodes simultaneously (which could cause a conflict).

For inserts this is less an issue because of auto_increment_increment  
and auto_increment_offset
