While I have a certain amount of sympathy for this view, it's often
the case that centralised storage isn't quite what you want. After
all, if always-fast is more important than always-right, we prefer
caches and such like. DNS is the obvious example there. And if
always-works is more important than always-fast or always-right, then
you have a very powerful incentive to keep things local.
That said, this case does sort of sound like money might be better
spent on improved communications that a humungous amount of work to
Rube up a Goldberg for getting all the data in every store. But
maybe we don't have the whole picture: maybe communications links
aren't stable in some of these stores, and can't be made so
economically.
