I looked for it a while ago. Appears the firmware does not support tethered shooting, nor does Panny have any plans of adding that feature to any of their cameras from what I remember reading. Almost any Canon or Nikon digital made over the past few years can. I wanted to set up a photo booth for my wedding with my GF1, but found I couldn't using any automated means. Luckily my step-dad's D80 does it.
