Hello,

Regarding question 1 about registry methods.

A single query point seems to be the most useful for users who are 
looking for information on a single or a couple of entries, even if the 
returned reply only contains a pointer to an RIR database.  Ideally the 
records may also be available in some full "list" for for those who are 
interested in multiple entries.  Today, the original /8 allocations and 
their subsequent assignments are not "cleanly" allocated to a single 
RIR, early "ERX" records have been transferred to different RIRs.  Today 
pointer records appear in the RIR databases for these records. Inter-RIR 
transfers will only increase the complexity for a enduser to find the 
current holder of an IPv4 address block.  Until a new method single 
query method supported by IANA and the RIRs is developed and deployed, 
multiple queries may be required to find a current IPv4 resource record.
Regarding question 2 about allocation methods.  A human based approach 
seems easiest at this point.  It is unclear how often this post 
exhaustion reallocation process will be used so an investment in a 
software approach doesn't seem to necessarily justified at this time.
