It turns out that when Sony said it was still "pushing some paperwork" before pushing Life with PlayStation that wasn't a euphemism for "don't hold your breath". Life with PlayStation is now available to download worldwide and I, for one, recommend you do so.
Life with PlayStation is acquired by updating Stanford University's Folding@home PS3 application, which it has assimilated. As well as folding, there is also what Sony calls the Live Channel, which provides a plethora of information all overplayed on a real-time updating globe view.
Some of the information available includes "cloud imagery (provided by University of Wisconsin-Madison Space Science and Engineering Center), along with weather information (provided by The Weather Channel), news headlines (provided by Google News™), and live camera images (partially provided by The Earth Television Network) of nearly 60 cities around the globe".
Whole browsing through this information, music can be played either by browsing and choosing specific tracks and artists, or by using Life with PlayStations automatic categorisation function to play tracks that fit into genres such as "calm" or "energetic". Although expect to disagree occasionally.
Life with PlayStation can be set to start up when the console is turned on - so you can see what the weather outside would be like were you not planning to spend the entire day in front of a console. Integrate an RSS feed reader I can add my own feeds to and I'll be happy!
