And they magically updated the software of all their
devices deployed out there? I thought not.

Sorry, but the world of IP network engineering is far bigger
than the in-crowd that hangs out on NANOG or ARIN lists.
The fact is that many IP network engineering folks maybe only
read Light Reading once a month, or look through the Networkers
program once a year when their budget request to attend the
conference is denied. And a lot of them don't speak English
very well, if at all.

It would help ARIN if they had a wiki page, even one on the
IPv6 wiki, that documented the first software release supporting
4-byte ASNs for every known hardware platform including stuff 
like Alcatel 7750, Huwaei, etc.

History shows that instead, they go back to ARIN and say that these
chocolate ASNs don't work, please give me a vanilla one.
