this is not linux based solution, however its still opensource :-) you can use two openbsd box as load balancers via pf and carp as a redundancy protocol in case one of your "load balancer" goes down.
and combine it with hoststated to monitor the status of your webserver (in case on of your webservers goes down) you can look at the hoststated(8) manual at http://www.openbsd.org/cgi-bin/man.cgi?query=hoststated and pf load balancing example at http://www.openbsd.org/faq/pf/pools.html and carp example at http://www.openbsd.org/faq/pf/carp.html and in case your using different isps on your webserver, you can use the openbsd loadbalancer to perform equal-cost multipath routing on all of your webservers cheers!
