I've floated the idea with a couple of operations people, and the small
sample that were interested are split between 4200000000 and the lower
proposed ranges.  Personally, I'm strongly in favour of the lower ranges,
but at this stage, the bikeshed doesn't need any more paint thrown at it.

Regarding Dave's concerns about allocating so many, this is a complete non
issue.  It's going to be a long while before we get from assigning 50k ASNs
to 4199999999.  Even if we do, we'll have generated such momentum in terms
of allocation that it will be necessary to move to 64 bit ASNs, which we
can do using a similar style of transition technology that we used for
asn16 -> asn32.  I.e. if you've reached 93% of the potential range, that's
well beyond the point at which you need to plan to expand the range.

So I'd say go ahead with 4200000000-end.  Thanks for taking Jeff's and my
comments on board - very much appreciated.

Nick
