Does anybody have anything neat to keep logs of what host gets what ipv6

You'd have to correlate ND information in the router to some kind of 
record of who has what MAC address at any given time. With SLAAC the host 
doesn't "get" an IPv6 address, it "takes" one.

This is often required for legislation compliance. DHCP does this well.

Which is one of the reasons why some of us want DHCPv6 support in hosts.

Agreed. In our environment Mac OSX hosts will either have to get the
necessary DHCPv6 functionality, or the customer will have to buy a 
router (which can then get DHCPv6 PD from us, and offer RA/SLAAC on
the LAN side).

SLAAC for our ISP customers just won't happen, for a lot of reasons.

I really do not get the lack of DHCPv6, the Apple 'it should be easy' is all very well and good, but it really does not 
help those people who have to run the networks at all. 

So for the foreseeable future SLAAC seems to be a requirement especially for WiFi operators for example who will have 
to support a multitude of unknown hosts. Has anybody found a usable method of achieving IPv6 address logs for such 
networks or will I just have to write some awful sniffer that spits out into a database that later on I'll have to 
correlate with WiFi AP RADIUS logs?
