How about better education *now*?  Might get that return rate down
substantially if there were some information out there about common
platforms and their support for 4-byte ASNs.  I asked at the meeting
if anyone knew of any "bgp for dummies" style books that talk about
4-byte ASNs and there was not a peep from the audience.  Let's FIX
that information gap.

Concrete steps:

1) ARIN to register fourbyteasn.info or something similar ASAP.
2) Set up mediawiki on same, just like getipv6.info
3) I will contribute my experiences, you can too
4) Make sure that this is referenced prominently in the AS templates or
   wherever else you go to sign up for an ASN these days.
5) profit

I believe a month is a reasonable timeline to have this up and running.
