Actually, for a ColdFusion Cluster, you just need more than one 
ColdFusion instance, not more than one webserver.  You don't even need 
more than one machine.  Two CF instances can be clustered and provide CF 
Application Server failover and loadbalancing for a single webserver 
box.  Really what is being discussed here is failover and loadbalancing 
for more than one webserver.  CF's web connector will handle sticky (or 
not) sessions inside the CF cluster regardless of which webserver 
answers the request.

You can use many of the hardware solutions out there to provide load 
balancing in front of your webserver, and there are some software based 
solutions as well.  Are you looking for specific brands of products 
beyond what have already been posted (for webservers)?   Or are you 
strictly talking about ColdFusion Clustering behind the webserver(s)?
