What options are available to load balance web service traffic on Linux with the ability to add or remove servers from the server pool without restarting the load balancer?

This post:

http://serverfault.com/questions/71437/mod-proxy-change-without-restart

looks like a very promising way to switch between two servers, but I don't know enough about mod_proxy and mod_rewrite to understand how/if I can use an external file to specify the BalancerMember entries for a section.

Are there other open source load balancers that support reconfiguration without restart?
