Justin Chapweske is the creator of Swarmcast, the first-ever "swarming" download technology — the grandaddy of technologies like Bittorrent. He's just released "Swarmstreaming" — a technology to make streaming go better if more people use it at once:
I'm proud to finally unveil swarmstreaming our third generation of swarming algorithms that are designed for the fastest downloads of web content and multimedia without any special server software or silly .swarm files. This is probably our most exciting advancement since the original invention of swarming.
The technology improves swarming by ensuring that the bytes that the user wants next are scheduled to be received next. So if they're playing back a video file, the bytes from the front of the file will be received first. If the user (or application) skips forward to the middle of the file, the bytes at the middle of the file will be prioritized. Thus, unlike first generation swarming systems like Swarmcast or Bittorrent, you don't have to wait for the entire file to download to do something useful with it!.
