Uhm, I think I mis-read the date on the original :( I thought they HAD
been passing them out, not WILL BE :( need more coffee :(

agreed, let's NOT do the v6 thing... do the 32-bit asn's give us more than
just 'more bits' ? :) (Sorry, I couldn't resist). So, yes, let's get
someone to start testing, I'd just caution on assigning the 32-bit asn's
for real-users, since much of the net might not be able to use them,
partial reachability will/could-be a problem.
