are we obligated, as a user of ARIN ip space, or per some BCP, to provide ad-hoc reverse dns to our customers with-out cost, or without financial obligation.
As noted, reverse DNS is pretty universally considered a normal operating practice, "part of the service". There is no IETF BCP that tells you anything about your business obligations, as in "without cost". However, I think you are correct that it is an important service to your customers.
One consideration: you might very strongly consider a mechanism (such as dynamic DNS) that enables you to not only provide names corresponding to addresses assigned, but to limit your names to addresses that are in actual use. The way my ISP-of-sorts (Cisco) sets up my home office address space, I have a name for each address in the block whether it is used or not, and if someone were to spoof one of the unused addresses the fact would not be noticed. Dynamic DNS or something like it would
