Obfuscatory marketing

I'm disappointed by Ed Felten's 15 line p2p app.
Ed is a great communicator, and a smart programmer, but in this case he has abdicated explanation for a sound-bite.
He could have written his minimal p2p app clearly and used it to teach, but instead he fell into the Obfuscator's trap of optimising for lines of code, to make a marketing splash.

Peer to Peer communication is a natural part of programming these days; writing code that looks as cryptic as that fails to make the point clearly.
