I consider this to be more of a minor technical issue. ARIN can certain 
provide an authoritative directory for the unallocated portions of its own 
allocations. And to answer your why question; because only ARIN has an 
authoritative and up-to-date view of exactly which addresses are and are 
not allocated. Rob Thomas is doing some fine work but he is just plugging 
a gap created by inaction on the part of the RIRs. 

I'd like to see RIPE, APNIC and LACNIC also set up authoritative LDAP 
directories for unallocated IP space at the largest aggregate level. I'd 
also like to see them all dump the quirky and antiquated whois protocol 
and move to LDAP as the standard way of querying their directories. The 
details of which data goes in which directory and whether or not to use 
referral LDAP or mirrored databases is something which I'm not concerned 
about. We know a lot about running a distributed directory from experience 
with DNS so I'm sure that a distributed LDAP hierarchy for the IP address 
space won't raise any major issues. There is a lot of LDAP expertise out 
there in the world, lots of books, multiple implementations with years of 
production experience and people running LDAP directories on a much larger 
scale than we need. There is no question that it would work, we just need 
the will to prevail against these problems instead of throwing up our 
hands and claiming it's too hard, it's impossible and it's not my problem.
