I'm looking at the guide here: http://www.howtoforge.com/load_balancing_apache_mod_proxy_balancer I was curious...if you have multi NIC's in the system..couldn't you set the entire system up as virtual hosts? Three NIC's in a system, 10.10.10.101,102,103. Load balancer on a VH bound to 101 with a doc root of var/www/load-balancer. Two more Virtual hosts sharing a document root (var/www/bcx3), each bound to a separate IP, 102, and 103. Vhost loadbalancer could be www.bcx3.local, VH 1 and 2 (mirrors) could be www2.bcx3.local and www3.bcx3.local. In my *theory* it should work..but this is all hypothetical. Any thing that seems to say it can't?
