Back in the late 1980s, large computer manufacturers such as Digital,
HP, IBM were pressured to adopt the future in networking: OSI as
transport and X.400 for emails.

These stacks were eventually developped and implemented.

However, the much simpler and more cost effective "Internet" ended up
winning and it didn't take that long for governments to remove the
requirements to be "OSI compliant" and accepted IPv4 and SMTP as the new

OSI and X.400 never gained much of a foothole and the millenium
generation probably never heard of them.

Is it possible that the same fate awaits IPv6 ? There is pressure to go
to IPv6, but if solutions are found for IPv4 which are simpler and more
easily deployed, won't that kill any/all efforts to move to IPv6 ?
