It's the lack of reality in operational policies that is the real source of frustration in ops communities. People are picking on shim6 because it is used as an argument to back the current policies at a time when it doesn't even have an early alpha-implementation to show for it. Policies built around shim6 may be ok in 5 or 10 years if or when it is mature with supporting technology to handle large networks, but not now. In the meantime we need a policy that can accomodate the need for multihoming of end-sites with *existing* technology. Without such a policy we will have anarchy with LIRs making their own policies (fragmentation) and people telling lies to qualify as a LIR to obtain independent blocks (unless there's a way to delay v6 deployment until there is technology available to back the current policy). //per -- Per Heldal http://heldal.eml.cc/
