This is a really weird service. It sends out semi-live streams (as
opposed to downloads) but it can be cached and made available later,
it's also peer-to-peer but needs a massive network or at least
massive amounts of peering.
With Bittorrent, it's typical for people to download faster than they
upload, and then continue to upload for some time after they've
finished downloading. This works very well as long as not everyone
starts downloading at the same time. However, for something with time
constraints this doesn't work so well. Either you're limited by the
maximum up speed, which generally isn't enough to support decent
video, or the peer-to-peer aspect can only take care of part of the
required total upload capacity so there must be additional servers to
take care of the rest.
I'm guessing the latter is the case here, and this new service works
much the same way as Skype in the sense that it will plunder people's
upload capacity for the benefit of the people running the network,
rather than being a real peer-to-peer service.
ISPs should of course welcome this, because when people start craving
their daily 2 GB fix you got them exactly where you want them,
especially in markets with little or no broadband competition.
