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
