Google's Dark Fibre Plans?

sebFlyte writes "According to news.com "Google is looking for Strategic Negotiator candidates with experience in...(i)dentification, selection, and negotiation of dark fiber contracts both in metropolitan areas and over long distances as part of development of a global backbone network." Is the search giant planning to build a global fibre-optic network?" Or perhaps simply use unused fibre that they can get for cheaper then from the datacenter providers; although at least from my talks with the datacenter folks, Google's not paying much per Mbps as it is.
