Then how is it better than simply using another webhead? In any case, we need to do heavy calculations AND transactionally update some state. It's possible to do this on slaves I guess with some trickery, but then what's the advantage over doing it in the app servers?

In that case, I'd have the app server connect to both master and slave, run the heavy calculations on the slave the same way, and then send the updates to the master.
