IPv6 Allocation Size

Congrats!  I see IPv6 is up and working in Mesa.

Quick question though:

Right now, I am using the /64 allocated on the wan interface of my router via dhcp6.  It works perfectly!   That amount of addresses (A bit over 18 octilion) seems nice, but there is one problem:

It's only one subnet.  

In order to use stateless ipv6 configuration, that's also the minimum size subnet that can be used on an interface.  If I split it across more than one internal interface on my network,  I will have to manually configure each device.  Bleah...

Now, for most people this isn't a problem, but I have my home network configured with two internal networks. One is behind a content filtering firewall so my kids are protected.  One is (more) open so the grownups in my household can surf the net and access services (eg: social networking) that is blocked for the kids.

Is there a way to get a slightly larger block of v6 addresses allocated for a home user?   A /63 would work, a /62 would give me room to grow.

Thanks!
