I'm not at the point of having to load balance (I hope I get there though :) ) - my site has only been online a few weeks.
I think Gossamer offer load balancing solutions, or if you don't wish to host with them I'm sure they can give you some great advice.
Thanks Paul, I really appreciate your advice. Best of luck with your site!
I think I have a good idea of how to proceed now.
