ok, I've fixed the meshfunction.xml file in the demo so it's defined
on cells (there are 8 cells). Running plot.py now gives

  File "/usr/lib/python2.5/site-packages/viper/viper_dolfin.py", line
  86, in plot_meshfunction
    raise RuntimeError, "Only vertex valued meshfunctions can be
    plotted"
RuntimeError: Only vertex valued meshfunctions can be plotted

Will fix the error message.
