Neither part of that surprises me. :-}
I'm *almost* convinced not to NAT IPv4, so far.

That's an interesting question indeed. The optimal solution here, of
course, would be for Worldcons -- which are planned 3-4 years in advance --
to get the right technical people in the loop with the property to see
when in the next 2 years (after a bid is confirmed) they plan to upgrade
the networking they have now... and make sure it will tolerate a "real"
worst case. The business case for the property, of course, is that
they're more salable to large technical conferences -- which makes them
more money. Question is, is it enough.
Or do I just overlay for the event.
