Yes - but the cost of the TOTAL SOLUTION - which includes replication
software, sysadmin time, programming time and testing, etc - is still
in my experience cheaper with one big database box than two smaller
boxes, if your only purpose is to get more thruput for the $$. This
is subject to change, of course.

Hardware is cheap. People are expensive. :^)

My preferred approach has been a big DB box and an array of
webservers connecting to it.
