Some questions, for my own clarity:

 1) Today, under current policy and practice, if ARIN becomes aware of
a block of IPv4 that is assigned/allocated to a defunct organization
(and therefor must be unused); you do nothing?
2) Will a POC for an IPv4 block assigned/allocated to a known defunct
organization be allowed to authorize transfer of those resources under
current policy and practice? What happens if there are multiple POCs?
3) If the community adopted a policy which stated that unused
resources assigned/allocated to defunct organizations should be
reclaimed by ARIN, could ARIN reclaim such space? Would you actively
work to?
