Thanks for the advice. In that case, I'll stick with the standard
approach of having a single SQL server and several web frontends and
employ a caching mechanism such as memcache as well. Thanks!

Man that sounds awesome. I need that now. So does that mean you'd
have one beefy SQL server for all the updates and everything writes to
that, and then you'd have a bunch of read-only servers and new data
trickles into them from the master continuously?
