I understood "offline" to mean that you needed to have access to the
whole input before you could start processing -- the canonical example
being the distinction between insertion sort (online) and selection
sort (offline). But you're quite right that the advantage of real-time
processing is pretty much moot because of the conceptual issue you
describe above.
