I've been lax in tracking what's going on with FeedTree, the Rice research project looking at P2P mechanisms for distributing webfeed content. A quick glance at the FeedTree weblog indicates healthy activity, including Calcium, a Python program which gateways FeedTree content into the Coral CDN (content distribution network, think Akamai). Projects like FeedTree can help alleviate bandwidth issues when a weblog publisher gets Slashdotted or otherwise stampeded.
