RIRs amenable to extra-regional use

[Doug Barton]

Jumping back into the time machine one more, um time. Back in the day 
the CW was that RIPE NCC was Ok with you requesting an allocation that 
would be used in other regions in addition to theirs (think large 
multinational corporations) assuming that you could justify the block; 
but that other RIRs required you to use the space strictly within their 
regions.

Is this still the case? Has RIPE NCC tightened up on this, or are other 
RIRs more flexible nowadays?
