A couple of old papers:
http://sahara.cs.berkeley.edu/jan2004-retreat/slides/bamboo-tr.pdf
http://www.iptps.org/papers-2004/li-churn.pdf

The first paper finds that a 1000-node DHT under heavy churn has a 900
byte/second bandwidth overhead, which grows logarithmically with the
number of nodes. The second paper compares the performance of various
DHT designs under churn.

A more recent paper finds that there are 15-27 million nodes in the
mainline DHT:
