I don't think the cost of IPv4 addresses has anywhere to go but up.
This mysterious Nortel/Microsoft transaction would seem to give
credibility to an assumption of increasing cost.

I think we can agree on this.  It is the natural result of exhaustion - scarce supply, ongoing demand.

It is important to note, however, that this is orthogonal to the registry management structure; we could have increased 
IPv4 acquisition costs with ARIN, or increased IPv4 acquisition costs with somebody else.

 Therefore, it stands
to reason that the cost of "database services" associated with being a
holder of IP addresses will be inconsequential.
If anyone thinks that won't be true for IP addresses, by all means,
let that person propose to overhaul the IN-ADDR system and possibly
the WHOIS database.  I do not think stakeholders will agree with their
views.  IP addresses are finite, and the cost of acquiring them will,
in all likelihood, dwarf the cost of publishing ownership/custodial
information or operational DNS records.

As I agreed above, acquisition costs will go up regardless.  The real question is total cost, which is (basically) the 
acquisition price plus the ongoing registry maintenance costs.

As one possibility, an overhaul might result in less expensive (or even "free") registry services being provided by 
brokers.  Assuming market prices aren't affected by the overhaul, the total cost might thus be lower with a broker 
versus ARIN.  Perhaps this is a small impact, but it's real.

More importantly, an overhaul to the registry system that facilitates liquidity in the market may introduce additional 
benefits.  (e.g. more predictable and/or lower acquisition costs)  I'm not an economist and I'm open to contrary 
arguments, but I see potential upsides to an overhaul that don't exist with the status quo.
