It contains a bar chart on past and predicted sales of TCP/IP and OSI software, whose figures surprised me, and I wondered what your IP group thought of them. They are in billions of dollars, and reading them off the chart they are approximately as follows: Year OSI TCP/IP 1991 0.55 1.10 1992 0.90 1.45 1993 1.20 1.50 1994 1.70 1.65 1995 2.50 1.95 1996 3.50 2.00 This question is not because I am wondering whether we should fork our 215 dollars (no way :-), just out of curiosity as to how others react. I have recently tended to treat OSI as a fading bad dream - am I due for a rude awakening? Cheers Brian
