This implicit conset is an interesting area, and I'd wager on seeing more cases like the OP. Last year a a friend and I spent an evening napkin-sketching a service that would piggyback on an existing js platform (ads, analytics, etc) but would do a little "extra" work performing quality of service tests. For example, it could do timed fetching of images from different sites to test promised speeds. So you could know how fast sever X could deliver to a user in Guatamala, when some other client in Guatamala connected to server Y.
