Two quick notes...

A group of five researchers primarily from the University of California have put out a new study arguing that P2P file sharing is not only back, but it never went away.

They assert that their measurements are more accurate by virtue of being ore complete. They apparently managed to measure traffic of all the popular P2P protocols (not sure how they measured IRC traffic, but I digress). In addition, they claim to have reverse engineered the protocols, permitting examination of traffic payloads.

And, since we're trading things anyway, Lessig's latest idea is to have us trade political speech - ads, in effect. The P2P Politics site is presently quite slow, resumably near-slashdotted and since it's serving up rich content it has to be urting for bandwidth, despite generous sponsorship from the Internet Archive. So far only pro-Kerry content has been submitted.

The idea of sending these things around in email is quite horrifying - email is too bloated as is. With luck people will just send URLs... yeah, right.
