When I was managing parallel development efforts of both TCP and OSI 
stacks, I don't recall hearing from any of my customers that they were 
concerned about address space.

This was in the late 1980s, long before the Web.

They were concerned about turn-key operations and interoperability. 
They got that from the TCP stack.  They never really got it from OSI.

Since OSI was the official strategic choice of countries and companies, 
but some had been using TCP, we started asking about their needs to 
tools to support their transition from TCP to OSI.  What we got back was 
a resounding and strong request that, instead, we provide for their 
accomplishing OSI to TCP transitions...
