Since most providers will likely need something larger than a  /32, I'm not a big fan of the idea of setting up an APNIC-Like Easy IPv6 "Push here for a /32" button.

Heather beat me to the punch, but I fleshed it out a bit more.  And, I 
agree with the warning button.

I tend to agree with the objection to just proving a one click for a 
/32, as it will not serve many providers very well.  However, what if we 
created a policy allowing for an even more simplified justification for 
larger IPv6 allocations based on a providers total IPv4 allocations.

Something like; if a ISP has an equilivant of a total /15 or more of 
IPv4, they need no additional justification to receive /28, and if they 
have a /9 or more they need on additional justification to receive /24, 
more than a /24 requires a complete justification.

Similarly, we could provider end-users a simplified justification for 
IPv6 assignments as well.  End-users with than a /18 or more of IPv4 
automatically qualify for a /44 of IPv6, or more than a /15 they 
automatically qualify for a /44, more than a /44 requires a complete 

Because there will probably be a financial impact, it should be 
implemented with maybe two clicks, for a provider select from /36, /32, 
/28, and /24, allowing the appropriate options base on a providers total 
IPv4 allocation.  This would probably allow an 80/20 rule to come in to 
play and provide for web page for IPv6 allocations appropriate for more 
than 80% of ARIN members.

The /18, /15, and /9 are just examples, you would want to look at a 
histogram of total IPv4 allocations by organization, before actually 
picking the cut-offs, but I think those may be at least in the ballpark.
