[arin-ppml] Policy Proposal 122: Reserved Pool for FuturePolicy Development

I don't know...maybe some such...

Perhaps a trendline estimate just before the Fall meeting.  If there is lots of uptake for transitional technologies in that time frame, then wait until the Spring meeting to assess again.....At each inspection period (meeting time?), estimate the amount of space needed against the uptake history out to 2yrs.  Same this amount and release the remainder if any to the pool then....or if it appears that all will be used with transitional technologies, save it. At the end of 2 years, either way, return what's left to the free pool.

Augment the list of non-transitional uses with a maximum allocation size (say /24) that may qualify over that same period of time.

Or, one could authorize an abbreviated 'emergency' allocation process for the list, given AC and BoT agreement and a 'last call' to PPML, addresses could be allocated.

I think it is likely to be obvious whether transitional technologies or IPv6 uptake are the predominant mechanisms going forward by end of calendar year '11.

One can't predict the future, but such a mechanism could provide some flexibility.  I do think that having addresses available for transition rather than same ol', same ol' is best.

What criteria would you use for "not being effectively utilized"?
Less than X% of the space given out Y months after exhaustion?  Less
than Z requests fulfilled under 4.10?

What other uses would be appropriate?  All valid requests?  Limit it
somehow to avoid giving out all of the remaining reserved space at
once to people on the waiting list?
