One of the IETF homenet participants is also one of the main OpenWRT IPv6 maintainers, and I'm pretty sure the latest 14.07 release of OpenWRT already supports SA + DA routing for multihoming. If you look at the IPv6 route table using the 'ip' tool, you'll see 'from' field prefix values, which is the source address prefix match.
