Replace "developer" with "deployer" and the answer is "yes", certainly. The headless support in 1.4 is much improved over previous versions - I don't know if the colour manipulation problems that another poster referred to are still present, but in the face of such glitches the person responsible for rolling out the app has to make an appropriate choice between Xvfb and headless, I suppose. If those problems are not still present, this suggestion seems harmless and potentially mildly beneficial. --=20 jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ ioctl(2): probably the coolest Unix system call in the world
