There are many ways to do it. It's not better but different. I personally would not like to make every application server (where the ltsp users work on) also a dhcp-server. One is enough. If we want to add more application servers we just replicate them and put them on the list of the available XDMCP servers. > ...the one that answers quicker gets the client resulting in auto load > balancing?

If your setup works for you just use and enjoy it. > I was under impression that OP wanted clustering of thin clients to > increase pool of computing power but maybe I am wrong here. I also wanted to give an example how this could be done. Additionally this could be easily integrated into standard ltsp.
