That is what we do here, both for performance and reliability reasons.

You are supposed to register YP slaves with the master, who then 
prods the slaves to update any changed databases. The 
belt-and-suspenders solution is to additionally set up a cron job on 
the slave(s) that updates the yp databases every day or so with 
ypxfr(8).
