The xx-small category was created to lower the costs of the smallest 
ISPs to something more equatable with what large end users would pay. 
There are only a few hundred ISPs (~400) in the XX-small category, with 
a /22 or less for IPv4. A /48 is not reasonable for an IPv6 allocation 
even for these xx-small ISPs, but A /40 while not the best seems 
reasonable. This would require both a modified version of this policy 
change and a fee schedule tweak of the xx-small fee category to "/40 or 
smaller" for IPv6.

Changing xx-small to "/40 or smaller" for IPv6 has added advantages for 
most end users as well.  The vast majority of end user assignments would 
fall under the xx-small category, something like 98%, at least looking 
at the data provided at the Dallas PPM.  And most importantly an end 
user that could qualify for a /44 or /40 wouldn't be tempted to only ask 
for a /48 just to save $500.

So as shepherd for this policy, I would propose to change it from /48 to 
/40 and change the rational suggesting that the board tweak the proposed 
fee schedule to have "/40 or smaller" for IPv6 in the xx-small fee 
category.  If there is consensus for this change by next week I will get 
the change put in before the April 5th publication freeze for the 
Barbados PPM materials.  Let me know what you think.
