Greetings, Mike.

Yes, someone is working on providing an open DHT service on PlanetLab!

Sylvia Ratnasamy, Sean Rhea, and I are working on OpenHash, a public DHT
service that supports a put()/get() interface. OpenHash will run on
PlanetLab nodes continuously; thus it will be a service, and not a library
that requires you to bring up your own DHT and keep it running. A good part of
the motivation for OpenHash is to provide a broadly accessible service that
offers a DHT routing layer, rendezvous, and persistent (key, value) storage for
those who want to *use* a DHT, but not *run* one.

We've submitted a (very) preliminary argument for and description of OpenHash
to IPTPS 2004; interested parties can find a draft at:

	http://www.cs.cmu.edu/~bkarp/openhash-preprint.pdf

We're hard at work on the first-pass implementation of OpenHash. While the
system isn't available for use yet, we hope to be testing an early pre-alpha
version in January.
