You beat me to mention pcp! :-) I really wished somebody would pick up the project and make it better. I have tested it a few years back and it was really fast. The general idea is that the host that has the original file will send to the neighbour and before that transfer completes the neighbour will send to its neighbour and so on and so forth. But it has some shortcomings: 1) If one host in the path goes down, you need to start over again 2) The command option/interface is a little bit awkward, if I remember correctly you need to specify all the hosts manually in the command line etc. And yes, I agree BitTorrent is a simple solution that works well, that is why we integrated BitTorrent as part of the distribution mechanism of OS images in SystemImager. However, it would be nice if someone actually wrote an application which eliminates the manual setup of the tracker, seed, etc. -- better yet, code something from scratch as BitTorrent cannot handle user/file permissions, and thus the way around it is to tar up the files you wanted transfer, and untar it after, which adds additional overhead. I look forward to trying out XGET, though.
