Thanks for the detailed explanation. That helps me understand the workings quite a bit better. I can only seem to modify the prefix length as well as my LAN IPv6 address if I disable DHCP-PD as far as I can tell.
Also, I noticed my WAN IPv6 address has a different prefix than my LAN prefix. Which seems like it would fit into the category you're describing, right?
All of this could probably be done via one router, but it would probably need something more advanced than what they're providing in stock firmware (ie: OpenWRT). With stock firmware, it seems it would be easier to setup different subnets with separate access points or routers added to the mix, which would make for a pretty cool project with a couple extra Raspberry Pi's.
I have to stop giving myself reasons to buy more of those things. :)
Regards, Nick
