[ih] When did "32" bits for IP register as "not enough"?

[Scott O. Bradner]

Dennis Jennings tells a story relating to this topic - he said that he was involved in an effort to get a set of OSI code 
produced & released along the same line as the Berkeley TCP/IP code but at the very last minute the vendor that
was going to provide the code, one that sold OSI code to vendors, backed out because they thought it would
be bad for their business model - the discussion might have been different if Dennis had succeeded, instead
that vendor’s business died along with the OSI protocols

Even teleco standards like X.25 ended up not being worth it.  Just not enough people bought them to make it so it was worth it.
