       -query host-name
               Enable XDMCP and send Query packets to the  speci­
               fied host.

       -broadcast
               Enable  XDMCP and broadcast BroadcastQuery packets
               to the network.  The first responding display man­
               ager will be chosen for the session.

       -indirect host-name
               Enable XDMCP and send IndirectQuery packets to the
               specified host.

This means you can't broadcast for a list. Is it needed that the user
gets the list. Broadcast will always take the fastest responding host
and will automagicly share the load to the servers.

If you still need it, you will have to write an option -indirect-broadcast,
which will send an BroadcastQuery and then an IndirectQuery to the first
responding host.
