To address the original question, there are several p2p companies focusing on optimizing p2p for internal distribution of software and rich media. In particular, Kontiki and Ignite both offer such services, and between the two have many of the Fortune 1000 as customers (Coke, Bank of America, Accenture, McDonalds, Canon, Burger King, etc.). Their systems manage not just the (p2p) physical delivery of the bits, but also the enterprise management aspects (e.g. sending the right versions of the right software to the right desktops, managing data flow in a way that works well on a corporate LAN, security, running the installs/upgrades, etc.). Addressing the Revision3 comment in the thread, I don't think that the "RIAA and similar organizations" had any problem with Revision3 using the BitTorrent protocol, but with them running an (inadvertently) open Tracker that was hosting 250K pirate torrents. The "attack" was pretty clearly a MediaDefender software bug in their code that monitors pirate torrents, multiplied by the large number of servers that they run, which unfortunately kicked in over a holiday weekend when nobody was around to fix it. Once MediaDefender was notified of the problem, Revision3 said that it was fixed quickly. So while you may not like what MediaDefender does for a living, it doesn't look like they were trying to DDOS Revision3 for using p2p protocols. - Laird Popkin, CTO, Pando Networks mobile: 646/465-0570 ----- Original Message ----- From: "Blaine Fleming" <groups@digital-z.com> To: nanog@merit.edu Sent: Wednesday, June 18, 2008 12:20:28 PM (GMT-0500) America/New_York Subject: Re: P2P agents for software distribution - saving the WAN from meltdown?!?

Has anybody used (and been successful at) a bit-torrent-like agent for fast distribution of LEGAL software (install programs of large-DVD size), across multiple sites, all over the globe, with bad WAN connectivity? I have read a couple of references online (e.g. http://torrentfreak.com/university-uses-utorrent-080306/) about such, but I am a little reluctant to do it in a corporate environment, especially in the light of potential misuse of such ... unless finding a way to install, use and remove the P2P agent, all in one shot ... catch 22, sort of (distributing the P2P agent, that is :)) ...

And we saw how it worked out for Revision3.com. MediaDefender considered them illegal and launched a Denial of Service attack against them over Memorial Day weekend. P2P is considered illegal and wrong by people with lots of money and that makes it hard to use for legitimate services. Because MediaDefender is backed by the RIAA and similar organizations they seem to be immune to prosecution. However, if *I* did the same thing then I know I would be locked up right now. --Blaine
