You're not alone regarding multiple video cards. That's another thing that I'm going to have to deal with. I just haven't gotten there yet.
I've used the -v option for multiple viewports(2, that is) and it works fine, but I have a bad feeling I'm going to have problems when I try to move to a third viewport rendered on a second video card.

However, if I start only one server on the machine with Multicast and with Unicast (Using the clusterwindow with only on window) I find that the Unicast version is much slower ...... Is there a workaround or is this a constraint I have to accept. The reason why I want to start two servers on one machine is, that I have two graphics boards (and four processor cores).... but OK. If its not possible I have to accept it.
