Yes, that will give you a proof of concept implementation.
And then what ?
First somebody has to convince Microsoft that they have to support this
The best you can hope for is a buggy version in Windows 2008 which
arrives in 2010.
Then around 2012 it might sort of work.
Open source OS's will be ready before that if IPv6 and similar is
Then you need to convince _everybody_, including the German government,
NASA, your local water-utility, the radiologist at your favourite
hospital, SSBN owning defenses, the CIA and _everybody_ else to do
the necessary system updates and upgrades.
Lets be optimistic and say that it's going to happen the time after
next time they buy new kit, because the 3rd party vendors need to
get their things working first.
So, realistically, we might be able to have a technical fix implemented
around 2050 -- 2040 at best.
You have to remember, this is far more subtle *and* intrusive than
just the IPv4/IPv6 thing, which so far has taken 15 years to get
absolutely no where (see RFC 1287, which has about the same level
of detail as the proposal Steve just published).
And also remember: IPv6 has had the "we'll run out of IPv4 addresses"
sword hanging over peoples head all along, we have no similar fulcrum
issue for leap seconds.
Compare this with "lets just forget about leapseconds" which will
give us some astronomers complaining about their instruments and
computers and potential problems that might happen 200 years from
now, but which also means "we don't have to muck about with all the
How do you propose to sell against that ?

Never attribute to malice what can adequately be explained by incompetence.
