If you request new IPv4 space, is ARIN going to require you to sign the 
updated RSA to get it?  (If you don't know, we'd have to ask ARIN 
staff.  I think there were some discussions about this back when we 
passed 2007-21, but I can't remember the details.)  If so, then you'd 
need to do so before getting IPv6 under this policy (2007-21) as well.  
If not, then ARIN considers your version current, and you're fine.

Actually, that is a really good point.  I think I'll incorporate it.

To answer your question, it is only that way for critical and internal 
infrastructure because when we passed those policies we wanted to make 
sure that ISPs could poke holes in their filters to allow CI routes 
through and filter II routes.

Yep.  The same is true of existing policy.

Actually, I think that's totally reasonable.  There are more than enough 
IPs in a /64 to do that for every registered domain on the planet.  Just 
don't expect that to justify getting more than a /48.  :-)

I'm still waiting for someone to come up with the magic metric here.  
But right now, I still think hosts are the best technical metric we have 
for defining the size class of a network.  I'm not really trying to 
define "how many subnets you need", but rather "are you big enough to 
fit into this size class", for purposes of routing table slots, etc.
