The new IETF homenet WG is discussing routing requirements for home networks; the assumption is multiple routed subnets. I would assume a /56 to the home. Not only do routing mechanisms need to be thought through, but also related issues like prefix delegation and management.
There's other interesting related challenges, like 'home scope' service discovery and naming of devices.
If you're interested, see http://tools.ietf.org/wg/homenet/charters.
