Since the "anycast" portion is over UDP, it avoids a lot of the problems (real or otherwise) mentioned here, and the HTTP is still unicast but distributed and can be made resilient to failure.
Of course, the DNS backend is then .. uh .. "de-coherent"? :-) But it works, and works well, in many currently operational configurations.
Does PPLB (or anything else) break this? I'm certain I could find things that would break this if I looked hard enough. But as I've said many times, reality trumps NANOG posts. Since this is a _working_ configuration today, I would say that disproves any claims that it cannot or will not work.
