Sigh, thanks for your help. I now have some more crap to throw at them to look at, and hopefully they'll give me some reply. There is a very profitable market for relatively cheap workstations running linux that can connect to one very expensive server running one copy of a modelling software with an appropriate number of licenses. I wish NVidia would realize this. I could be a vehement supporter or naysayer either way depending on how this turns out.
