Bittorrent the Protocol
Apparently Opera browser is embedding a Bittorrent client in its next version. Kewl. Hopefully other browsers follow suit.
But that's it. Until web servers becomes Bittorrent capable themselves, Bittorrent will remain more a software than a protocol. Otherwise, it'll be smooth and transparent like HTTP compression headers that most of us already benefit from without even realising its there.
And from the bickering, looks like nothing is going to change (Maybe it'll take a MS implementation to Apache into action?).
