I believe that message was sent, and received.  While the vendors are
not quite where I would like them to be in terms of availability, I
don't think sending more messages at this point is going to be

I believe there is value in knowing the date, but it need not be
arbitrary.  For instance, 16 bit ASN's will run out in less than two
years it would appear, which is a fairly well known date.

AFAIK, the vast majority of the vendors have working code at this point.
The issue is that it may not be in all of the various forms they release
code yet, but that is going to be a function of their release cycles and
no amount of policy will change that.

I'm not sure I think it will surprisingly reemerge, as the run-out date
is fairly well predicted, but it will re-emerge.  From an ISP
perspective, it only takes one customer needing this feature for you to
have to go off and do the work to figure out what you need to do; so I
don't think a short reprieve makes us really go backwards in terms of
support.  If anything, it may provide for a smoother transition as
providers can roll out the code in normal cycles, rather than a router
at a time as customers demand it.

This is the only area where I have some concern.  I think folks should
be able to show up and say "I want a 32 bit ASN" while there are 16 bit
ones still in the free pool, be it for testing or because they want to
leave 16 bit ones for those who need them.

That said, all indications are that you could probably count the number
of folks who would request and use 32 bit ASN's on one hand during the
timeframe in question.  Because of that I have my doubts it is worth the
community, ac, board and staff time to pass a policy at this point.  We
do have many other issues on the table. :)
