I'm in a similar situation, and no, I don't know of a nice and easy way of doing this with current software.

Pre-generating reverse records for any possible IPv6 address in your prefix(es) isn't going to work. Adding it to your own services/servers such as email servers etc, that's easy. But how can you know which of the 2^64 addresses your customer is going to be using?
I've been toying with some ideas, not sure which one would actually work the best way:
- don't add any IPv6 reverse records for customers
- you could take the overhead of letting your customers either ask for specific reverse records to be implemented (through customer service? self service web interface?)
- if your customers get assigned addresses from DHCPv6, you might consider letting it update the zones for you
- in theory you could delegate the responsability for reverse records in the customers prefix to them, but I doubt many customers would actually bother running their own nameservers for this.
- perhaps some alternative nameserver software is capable of generating the reverse records on the fly, based on some template, if there's not a specific record already defined?
