No,  I don't have specific sources.  But the software that supports
"interactive features" hasn't changed much.  Display files today are pretty
much the same that they were 10 years ago.

I too am impressed with IBM's implementation of TCP/IP.  But it seems to me
that sockets support more batch services than interactive.  To get a feel
for how much sockets are used, and what they are used for, just consider the
services that are started by the STRTCPSVR, STRHOSTSVR, STRMSF, etc.  Then
estimate how much Websphere, Java, Domino, DDM, and PASE rely on sockets.
Most of the cost of sockets is probably not for Telnet.  Then consider that
Client Access Express generates revenue on top of the hardware revenue
credited to interactive features.

I still think IBM prices are based on competition and value proposition.  I
think cost has some relevance, but not much compared to the other.
