This should probably go in the Glutton For Punishment forum, but I couldn't find it.
Has anyone tried running Autodesk's Inventor CAD program under VPC recently? I use Inventor at work on a 1.7 GHz Xeon, but have run it successfully, if slowly, on a 350 MHz PII. I just got a 1 GHz TiBook so I'm thinking it might be a usable platform if there aren't any hardware emulation problems...
