YA USGov computer mandate that will be ignored (Score 1)

The US Federal government has a long history of imposing on itself mandates
for new computer technology, mandates that are ignored and never enforced.
They all set a date after which every agency may buy only computer equipment
or software that contains some new not-yet-mainstream technology.
The dates come and go, and agencies continue to buy what works for them.

Examples:
1979: mandated no more RS-232, only RS-449, for modems and computers that
connect to modems. Today: have you ever HEARD of RS-449?

1989: mandated every new computer that communicates with other computers must
use OSI protocols. Today: TCP/IP rules.

2000: mandated end of use of RSA (the PKCS#1 form used in SSL) by August 2001,
and the adoption of a new form of RSA (ANSI X9.31). Today, PKCS#1 rules.
The standards bodies haven't even considered switching.

2005: mandate IPv6 by June 2008. We'll see.
