I think the question comes down to whether Sydney needs the entirety of the web page it's referencing or whether it get by with some much more compressed summary. If Sydney needs the whole web real time, it could multiply world web traffic several fold if it (or Google's copy) becomes the dominant search engine. One more crazy possibility in this situation.
