I don't know what I was thinking last night, but I believe I had SLAAC + DHCPv6-PD working myself, but wasn't satisfied. =) I'm not comfortable using SLAAC for WAN addresses in a service provider environment. I do DHCPv4 relay today. DHCPv6 relay worked perfectly on an PVI, but with a SVI with it was very much hit and miss, such that now CSCtl77398 has been created. Enabling "ipv6 multicast-routing" has dramatically improved the success of DHCPv6 relay. So while the bug is not fixed, it's good enough that I can continue with preparing for a trial.

Have you looked at D-Link's DIR-825? It has most of the things you're looking for. The DIR-655 is a more affordable option.
Haven't had the chance to look at that one. Will check it out.
In regards to (2), is it even possible to do DHCPv6-PD on with a SLAAC WAN?
It had better be, as IOS 12.2 SRE only supports SLAAC + DHCPv6-PD. Most of the Cisco documentation I've seen, says that is their beautiful layout. No more proxyarp/nd. Instead, assign a /64 to each subinterface, perform SLAAC, then hand out prefixes via DHCPv6-PD if someone needs a prefix.
In regards to (3), I have that working on SRE, but with an external DHCP server.
Yeah, I could see the forwarding code supporting it. Cisco documentation stated proxynd with rbe/unnumbered vlans isn't what they support. How did your tests go mirroring the v4 method using dhcp forwarding with the v6 method? Jack
