[arin-ppml] Large hole in IPv6 assignment logic

I can't justify the new block.  I have a few thousand potentially 
addressable hosts, definitely not enough to fill multiple /48's, the 
same as pretty much every other network out there with a very few 

I went the other route, as suggested by many people, and attempted to 
submit my application as a LIR, given that we run a separate 
transport/transit backbone from our content serving network (two 
separate AS's, one providing transit services to the other).  I was told 
that we don't meet section of the NRPM -

"be an existing, known ISP in the ARIN region or have a plan for making 
at least 200 end-site assignments to other organizations within 5 
years.", however when pressed as to how 10310 or 15169 meet that 
requirement (specifically 200 end-site assignments to other 
organizations), I got no answer.  The reality of it is that neither fit 
that description - Yahoo and Google provide transit services to 
themselves only, and while they may have 200 end sites, they are 
definitely *not* other organizations.  I do not understand why ARIN 
management would have made exceptions for these two companies (and 
probably many others).
