The debate there will be around the preferential treatment that larger ARIN members get (in terms of larger allocations, lower per address fees, etc), which Kremen construes as being anticompetitive via creating artificial barriers to entry. That may end up being changed.
Your statement about preferential treatment is factually incorrect. Larger ARIN members do not get larger allocations. It is the larger network infrastructures that get the larger allocations which is not directly tied to the size of the company. Yes, larger companies often have larger infrastructures. However, ARIN gives the addresses based primarily on the number of hosts attached to the network infrastructure. It has been argued in the past that ARIN's policies are prejudiced AGAINST larger organizations because the rules do not properly allow for the scaling overhead necessary due to the complexity of larger networks. As for fees, there are no per-address fees and there never have been. When we created ARIN, we paid special attention to this point because we did not want to create the erroneous impression that people were "buying" IP addresses. The fees are related to the amount of effort required to service an organization and that is not directly connected to the number of addresses. --Michael Dillon (no longer in any official ARIN capacity.
