I'm going to third this suggestion.

I ran a LVS cluster at a former company for several years - built on
cast off hardware (so the cost was just my $TIME). About a year after I
left, they dropped this down and put in place a "real" solution that
cost just a bit more then $20k. The site went from 0% downtime over a 4
years to periodic outages... (of course it only went down during peak
use :-)

LVS is surprisingly robust... and you have direct access to the
maintainer of the HOWTO!

<aside: shouldn't Joe give a talk about LVS?>
