[arin-ppml] IPv6 Multihomed networks

For my own edification, why are we treating IPv6 like it is a rare and precious commodity?  Wouldn't it actually be better for the community if the requirement for the base level IPv6 allocation were simply filling out the request form and paying the fee?  

This isn't like IPv4 where we needed to make sure that anyone who ever got any would actually use it..  I would suggest that the minimum assignment of IPv6 should be available simply for the asking (filling out the form with contact info) and payment of minimum fees.
