This is bit torrent. At least that is what the program I used resembled quite extensively. The download manager by akami is essentially a bit torrent system. I had 4 seeds on my download
Then where's the .torrent file so I can use a proper client?
The akamai java-based client does say it's using X other connections, but that doesn't necessarily mean a p2p protocol (if it was p2p, I would have expected a much higher amount of connections). It's normal for http and ftp downloading to use multiple connections to distribute server load a bit, as well as giving better speeds.
With a .torrent based approach, I could've just dropped to .torrent to my linux box and shut down my workstation... and gotten somewhat better speeds (1.7MB/s here through akamai which isn't bad, but my adsl connection can reach 2MB/s stable with well-seeded torrents).
