I have a problem with this language:

"Downgrades of any IPv6 allocation to less than a /36 are not permitted 
regardless of the ISP’s current or former IPv4 number resource holdings."

Downgrades include in my mind a return, and thus a downgrade to 0.  This 
language seems to lock in anyone who has ever requested IPv6 space.

Does this make a request for IPv6 space from ARIN like the Hotel 
California, where you can never leave....

If I were one of those ISP's with a /24 of IPv4, and I took the minimum 
allocation of IPv6 which raised my fees to $500 from $250, does this 
language make me continue to pay $500/yr even if I decide to return all my 
IPv6 resources to ARIN, and either get IPv6 space from my upstream or 
forgo use of IPv6?
