What is the best way to provide redundant connectivity to SMBs with IPv6? Using v4 with NAT is easy with most routers but v6 is harder. Shim6 seems to be a good idea but looks to be a dead duck. People in that thread were advocating full AS and BGP but I don't think that is easy for most SMBs unless their IT support is top notch and trained (which lets face it, most don't even know how to screw in a lightbulb). It also may mess up global routing tables causing them to get much bigger.
