From the PDTP website:
I'm not familiar with Portage at the development level, but do others think something like this could be a viable option?The Peer Distributed Transfer Protocol (PDTP) provides a method of transferring files using peers to aid in distribution of content, similar to BitTorrent. PDTP servers manage a directory heirarchy automatically, making it somewhat more like HTTP or FTP, and support a number of other features such as metadata rich directory listings and support for file integrity validation through the use of DSS signatures. For more information, please see the FAQ.
