We have a customer who was assigned some PI IPv4 space by Paetec back in
mid-90's and who has continued to announce the blocks, even though their
relationship with Paetec ended a long time ago.

Is this a common situation? Does the customer risk having that space
reclaimed by Paetec at some point, or is it safe to assume they will
continue to be able to route trouble-free for years to come?

They should plan to renumber out of that space in the very near future.

This is an excellent time to plan to renumber into 2001:: if they haven't
such plans already. :)

Well, somewhere in 2000::/3, anyway… It might be somewhere within any of the following blocks: 2001:400::/23, 
2001:1800::/23, 2001:4800::/23, 2600::/12, or 2610::/23, 2620::/23.

All of which have been delegated to ARIN by IANA.

As to the PI/PA question… There were PI blocks issued by LIRs (ISPs) in the years after the initial implementation of 
CIDR and before (and possibly for some time after) the creation of ARIN. My blocks 192.159.10.0/24 and 192.124.40.0/23 
are examples of such blocks which were originally issued to me by Netcom and PSI, respectively. They are now correctly 
documented as "Direct Assignments" in the ARIN database and covered by LRSA (which I now regret given the recent fee 
restructuring).
