Well then experiment with me.  I've been wanting to do this, but I need
to rework the applications so that I don't have them doing all the same
thing.  

I have one application that looks for new rows in table A and then sends
out email.  If I have a cluster of these servers. each running that app,
how do I keep them each from sending out the same email?

My issues are more application issues than getting clustering to work.
I'm sure I can do master-master replication.  I need to get the programs
to behave.
