Along similar lines, you could also run vic in a virtual frame buffer
version of X (Xvfb). Using Xen or some other machine virtualisation
system, this technique can be used to have a "separate" capture
machine along with a display machine both in the same physical box.
For an example implementation, see http://www.vislab.uq.edu.au/
research/accessgrid/software/xenag/). These days, Linux KVM (kernel
virtual machine, not keyboard/video/mouse) is probably a better way
to do the machine virtualisation. I believe you need kernel 2.6.20 to
do KVM without patches (and supported cpu).
