I almost made a comment that the PSTN is really (as far as routing is
concerned) lots of disparate networks with no 'global view' of the
problem. It can be argued (and randy likely will, or bmanning even)
that the Internet doesn't have a single view either... There's loop
protection in the routing data, which the PSTN doesn't really have.
(which is a side problem)

doubtful... probably me missing a terminology collision :( It also
depends on how Tomas was defining his problem.

I still say the PSTN and Internet are apples/oranges in so many ways
you can't use them in an comparision.
