What I'm trying to do is run a single visualization application per X server to enable distributed rendering of some very large scientific datasets. Each application uses the hardware to render its piece then composits it with the other programs on the cluster
via TCP/IP.
<div>So basically instead of "xterm" below there will be "//usr/local/tools/ensight-92/bin/ensight92.client -some fancy -args"</div>

Ah hell, now it's just working. How strange. No doubt as soon as I send this it will stop working again.

Never mind! Thanks. <br>
