it is possible with the current vms?

I think not, but I think its really really close. �Basically instead of the VM responding to -headless you'd have the image respond to -headless and arrange that all the code that starts-up the GUI window is called from a new primitive, say, openDisplay. �Right now (I think) the VM decides whether to open up the main display or not, and does so by looking for a -headless argument, and if not found, opening the GUI window which remains blank. �Ask Igor to trace through the startup code on each platform, looking for "headless" in the source and I'm sure he'll find it.
