Ok, I would propose something like:
"full time connection to two or more providers" should be satisfied when the network involved has (or has contracted for and will have) two or more connections that are diverse from each other at ANY point in their path between the end network location or locations and the far end BGP peers, whether or not the two or more connections are exposed to one or more common points of failure, as long as their are any failure modes for which one connection can provide protection against that failure mode somewhere in the other connection.
Whew :)
I am sure someone can say it better!

FWIW, two GRE tunnels over the same physical tail circuit to different providers on the other side would satisfy that condition. Frankly, I don't believe that your expanded definition changes anything from the current state of affairs. Owen
