Query: Simulation Software: Then, Now and Virtual Observatory   Like hardware, evolution of software has had a major impact on the field of
particle simulations. This paper illustrates how simulation software has
evolved, and where it can go. In addition, with the various ongoing Virtual
Observatory efforts, producers of theory data should think more about sharing
their data! Some examples are given of what we can do with our data and how to
share it with our colleagues and observers. In the Appendix we summarize the
findings of an informal data and software usage survey that we took during this
conference.
