        What do you want exactly? To make sure the indirect queries
always work (by providing high availability for the indirect
queries)? May be if you hit the VIP:177 with these indirect queries
you can then select the real X client. May be you can -broadcast
to all hosts in the LAN without using LVS? You can even use software
that can use a list with hosts to receive the broadcast message from
your X servers, in your case the hosts you try to use as XDMCP
real servers. I assume these broadcast XDMCP capabilities can help you
without using LVS?

        I assume you have more hosts :) What kind of problems?
