I'm reading your statement as if you got the logic backwards - because this
doesn't rule out "pipe from one provider and tunnel across same pipe to another
provider, because the tunnel is diverse after it emerges from the first
provider's pipe. But since you know *up front* that the two connections have
fate sharing, it's not clear that it's "good enough" multihoming to count as
two *real* full time connections.

As long as there is *A* failure mode?  Hmm. <invents a movie-plot failure mode
involving crazed ninjas with katanas loose in a switch room at one provider>.
Yep, it's unlikely crazed ninjas will attack the switch rooms at both providers.

I'm pretty sure what you intended to say there isn't what I read it as...
