Note that I am speaking here as an ARIN member and resource-recipient (PCH), AND NOT as an ARIN board member.  I have 
no inside track on the interpretation of ARIN rules, and don't pretend to.

We do so, without any problems.

We do so, without any problems.

We do so, without any problems.

HOWEVER, we've been told in the past that space received from ARIN and used outside the ARIN region did not qualify as 
"utilization" for the purposes of justifying new allocations, nor were locations outside the ARIN region entitled to 
new allocations.  We were told to get space for POPs outside of ARIN's region from the other respective RIRs.  And 
indeed, those other RIRs have, by and large, been quite cooperative with giving us space for use within their regions, 
even in the cases when we had no business incorporated entity within their region.

This experience is two or three years old, now, so interpretation and policy changes may have had some effect since 
then.
