[ppml] Markets, pricing, transparency, 2008-2 / 8.3.9

To summarize, you are suggesting that we need to have ARIN collect and 
publish price information on each IPv4 transfer transaction, correct? 
Currently 8.3.9 reads, in part, "ARIN will also publish a log of all 
transfers, including block, transferor, transferee, and date", and you 
want to add "price paid" to that list, right?  Do you have any 
suggestions as to whether/how ARIN should concern itself whether the 
price reported by the transferor and transferee is accurate?

An assumption we made in the proposal was that transparency would be 
achievable through the ARIN-operated listing service: both transferees 
and transferors would choose to list there, and would provide a 
listing/offered price on each entry.  This would provide ARIN and the 
public information as to the prices people are willing to pay/accept, 
and one could assume that most transactions would occur between those 
two prices (i.e. that most people wouldn't pass up a better deal).

Can you clarify how you'd propose to enforce transparency, and what 
impact you think such enforcement would have?

Thanks for your input,
