[ih] OSI and alternate realiv

[John Day]

The PTTs were still stuck in the 20 year turnover of equipment and it was changing lot faster.

Minitel had nothing to do with OSI. It was already in the works when it started. That was how the Session Layer got stolen and why there was TP0.

What is even funnier was WAP was Videotex all over again and just as bad the second time around.
