As I understood Grid, it is a decentral technique, like p2p. And that is why everything will get faster and faster with Grid, but it is still limited by your bandwidth.
Well when referring to this:
This is because the Internet has evolved by linking together a hotchpotch of cables and routing equipment, much of which was originally designed for telephone calls and therefore lacks the capacity for high-speed data transmission.
By contrast, the grid has been built with dedicated fibre optic cables and modern routing centres, meaning there are no outdated components to slow the deluge of data. The 55,000 servers already installed are expected to rise to 200,000 within the next two years.
it sound like some kind of new technique to transmit data via fibre-optic cables. Otherwise this wouldn't have been special in any way and wouldn't have needed special grid servers but just the common ones for fibre-optics...
