[ncc-services-wg] Charging for PI space?

I'd like renew the discussion of PI address space and how it affects ones' RIPE category: http://www.ripe.net/ripe/docs/ripe-331.html Suppose a LIR was asked by a customer to acquire PI address space (/22) and the customer had justification for requesting it. What do LIRs charge the customer for doing this work and therefore increasing their "billing score" for one year? Regards, Hank
