I have a probably dumb question. Even if a company were of large enough
wallet to have, say, a single redundant connection, how could it
evaluate the partition problem in order to choose the "best" connection
(where "best" is a function of overall connectivity, say) ? It seems to
me that that's a really, really hard problem. And surely isn't a static
one-off kind of calculation, right?
