bittorrent and rss. Since first posting about it, I've been thinking more and more lately about the possibilities of combining rss enclosures and bittorrent ad-hoc p2p networking. The more I analyze the setup the more I like it.
RSS enclosures enable pre-caching of a payload on the receiving end of a file transfer.
Notification of an updated payload feed is deferred until the file has been downloaded.
In my scenario, the payload is a bittorrent url, which fires a BT download helper application (possibly built into Radio?).
Opening the bittorrent file (approx 40k in size) connects your computer to an ad-hoc network of people sharing the same file. Every bit of the file you download is immediately made available to upload to others. In effect, you are downloading from multiple upload sources. All bandwidth in the network is dedicated to the transfer of that one file, which could very well be a 400 mb mpeg.
The downside of this type of file transfer network is that eventually availability will die off, leaving to archive to point to.
My gut tells me this could even be a standalone application. Just drag and drop your homemade tv show on a folder on your desktop and away it goes, sending an xml message to thousands of subscribers, who will automatically form a sharing network dedicated to distributing your content! All without the cost of centralized distribution.
I've asked Marcus to help me develop this functionality in Radio, to get us going. Hopefully other developers will think about adding the rss-bittorrent connector bits onto their aggregators and weblog software.

Slashdot | Command-Line Crypto From Phil Zimmermann, Again. A few months ago, PGP creator Phil Zimmermann became a reseller for the current graphical version of the software he originally spawned, produced by PGP Corporation. Now, Zimmermann has just started selling through his own website a modern command-line encryption product called FileCrypt, which has its roots in an older version of PGP. Confusingly enough, this software is produced by a company called (Veridis), and doesn't say PGP on the box, because legally it can't. Network Associates, which acquired PGP Inc. in 1997, still holds the rights to that name; when NAI spun off PGP to PGP Corporation in 2002, they held onto the command-line version. OpenPGP, for whom Zimmermann serves as a technical advisor (as well as a reseller), is contractually unable to sell a command-line version. (He is on the board of Veridis as well.) But why introduce a text-only version of utility software, anyway, when the GUI-fied desktop version has been maturing for years and costs less? [Privacy Digest]

CIO: Off the Charts. The University of Illinois Medical Center won an Enterprise Value Award because of a brilliantly executed change management strategy, through which it managed to get the toughest users on the planet to lift their heads up long enough from the work of saving lives to change the way they deliver care to patients.

Princeton University: WebMedia - Lawrence Lessig - The Creative Commons. Thursday, February 20, 2003 - 8:00 pm, Helms Auditorium (McCosh 50) Links will be activated 15 minutes before the start of the event The Creative Commons: Every society depends upon a space for independent, well-regulated social criticism. The public domain is crucial to supporting that space. In this lecture, Professor Lessig will map a threat to the public domain that is increasingly weakening this opportunity for social criticism. As an unintended consequence of the reach of copyright law, the opportunity for social and political criticism has been weakened. The broadcast will be in Windows Media Player and RealVideo.
