There are several layers of load balancing that need to occur.

 A web server load balancer (hardware or software) needs to make a decision on 
which web server to send the traffic too.

 Then the web server's connector is responsible for figuring out which instance 
to send the work packet too.

 The purpose of clustering CF together is so that all of the instances are 
available to all of the web server connectors and to keep the session 
information (all of it, finally, in CF8) replicated across all of the physical 
servers.  This directly will relate to the experience of your users if 
something in your site fails.  Hopefully, if you've got the cluster built 
correctly, they'll never see the outage when the load balancer or connector 
kicks them to another instance.
