      $9.3M was the costs January through August 2011.

Registration services handles the requests for new blocks, but also 
provides the registration services help desk (7 AM to 7 PM) for all 
registry users, both new and existing.  While the number of requests 
does impact workload, it is a secondary factor compared to the 
requirements for staff the helpdesks and helpdesks at ARIN and NANOG 
meetings.  These are fairly fixed and included in core registry costs.

Registry costs are fairly fixed (engineering operations/sysadmin,
software/hardware depreciation and maintenance), but our some our
costs (for storage, licenses, bandwidth, etc.) do grow with number
of registry records.

No relation to costs.  We couldn't afford to maintain a single IPv6 address 
block in the registry if there were any costs that were proportional to 
number of IP addresses in the registry.

I hope this information is useful - please let me know if you need anything
else...

Thanks!
