For Dave Cheriton and Alex McKenzie:

1. ST was an experiment in real-time communication on the Internet.
   The ST protocol, which operates at the level of IP (adjacent to it),
   had special features to support multicasting for voice conferencing,
   for instance.

2. It seems to me that the more useful debate would be whether ST or
   Muilticast or perhaps something along the VMTP lines is the more
   suitable for carrying out the kinds of explorations that Claudio
   wants to pursue. ST has a lot of features that emerged from
   pracitcal voice conferencing experiments which included long-delay
   satellite channels as well as the terrestrial Internet and, if
   memory serves, at least one packet radio network.

3. Yes, Alex, you can claim to be one of the IP and TCP developers -
   it was and continues to be an effort engaging the ideas and skills
   of many people.
