Me too, and it works very well, but only with directly connected 
crossover cables between the servers. I wasn't able to get it working 
correctly via a switch on the replication network. It went wrong when I 
disconnected one of the cables.

You might be able to get it to work better than me but I'd advise you to 
test failures like that before putting it into production if this is 
your use case.

Btw, I found using jumbo frames (setting MTU=9000) made a huge 
improvement to performance here.
