No, this doesn't work, at least with normal routing gear.

IPv6 subnets are ALWAYS exactly 64-bits, and the routers know it (actually, the IP stack in the OS usually knows this). Sure, with some linux routers you can hack things up and sort of get that to work, but it really screws up more things than it can help.

I'm not really sure why I would need multiple subnets in my home, and go through the expense of having routers to separate them and separate WiFi APs for each.

If you just want "logical separation", or something to ease your firewall rules, you don't really need a separate subnets.

Native IPv6 should work fine if you have a DD-WRT build that supports IPv6. Sure, you need to configure RADVD, but the GUI has a place to do that. 6to4 and 6RD work, I've tested them.

You are right about DD-WRT and 6to4 or 6RD: You need to write a config script that connects. It's ugly. But most Linux's are pretty ugly about IPv6. I would be nice if they make the GUI handle this. But you can get it to work.

You are very confused. A /64 is enough space for every network device ever built or will be built in our lifetime to be part of one home network. And you think that is too small? That you will run out in a jiffy?

IPv6 works. Subnets cannot run out of addresses in any foreseeable future. Business will get a /48 or at least a /56. They won't have a problem.

All of the IPv6 problems are in the transition.
