While I do support Proposal 121, I do have a concern/questions about Owen's first point.

I think it is important to be careful here about two things.
1) While removing any obstacles or discouragement from subordinate ISPs receiving PA space is a good thing, we should take care that we don't end up discouraging the same ISPs from
obtaining PI space instead.  I do not believe the current wording does this, but I think it is important to keep the point in mind for future edits.

2) After the SWIP topics of this last year on the PPML list, I have this impression that record keeping across the ARIN region is a bit inconsistent and lacks automation.  I hate
to bring up what seems to be a dead-horse topic, but should SWIP policy be modified in regards to any difference between subordinate ISPs and large end users?  Should there be a
policy about SWIP auditing?  Does a multi-homed subordinate ISP, which qualifies for a /32 of PI from ARIN, qualify to get a /32 PA from each of its providers?  Given the size of
v6 are we even concerned if they do so?  And what would that do to global routing table growth?

and a personal ignorance question:  Does a subordinate ISP with X aggregate allocations advertised through Y direct upstream ISPs end up adding X x Y routes to the global tables?
