But you wouldn't want to do this again every time the network's
topology changes, would you?  It's not the (user level) programmer's
job to do this, such optimizations should be done by the OS. Such a
scheme is most useful when versatility is important (e.g., accessing
parts of a databases straight off people's laptops, wherever they may
be at the moment).
