Since we need to configure unique prefixes to each router in the home anyway, it should not be any problem to do the same for a router ID (or even just use an address from the configured prefix as router ID, which should then be unique). A while ago, there were some plans in AUTOCONF to specify how to use DHCPv6 (-PD) in a multi-hop network for configuring prefixes in the network. As in a home network, I assume there is always at least one border router with the global prefix, specifying something like that seems to be reasonable for me (in a MANET, that can be more difficult, because there is not necessarily such a central entity as the border router).
