Providers who don't wish to be leap-frogged have to make business
decisions about unserved and underserved demand for which they don't
already have an effective product.

That's not a particularly compelling counterpoint. We have a mechanism
for multihoming: BGP. We have a mechanism for flying to the moon:
rocket ships. At a strictly technical level, either could be made
suitable for use by John Q. Public. In both cases the cost
attributable to John Q's desired activity, when using known
techniques, greatly exceeds his budget.

That having been said, I'd be very interested in your take on how FTL
would change intercontinental peering patterns. How would dropping all
links to a 0 ms latency change the ways in which we choose to
interconnect and why?
