Introduction
  • The field of Web conferencing software is growing
    at a breathtaking pace.
  • In the summer of 1994 there were exactly two
    products in this category, both of them rather
    primitive freeware packages.
  • Today there are well over 60 commercial and
    freeware products, many of them quite
    sophisticated, that support conferencing on the
    Web in one form or another
