open source program about DHT-based memcache

[shower]

I am a new guy focusing on memcache. We know that original memcache is
a non-DHT-based system, that is to say the cache servers can only
store resource in a simple distributed way with consistent hash , but
all the servers can not contact with each other.
I 'd like to know whether there is some kind of modified memcache
program supporting some kinds of DHT algorithms, such as Chord , Kad,
etc.

I have implemented a memcached based on Overlay Weaver.

Overlay Weaver: An Overlay Construction Toolkit
http://overlayweaver.sf.net/

It is an implementation of structured overlays. Today, about 500 nodes
are running on PlanetLab and construct a DHT. Note that the DHT
supports OpenDHT client protocol and HTTP access, not memcached protocol.

The implementation has been in the CVS repository but not released as
a new version because of temporary lack of test environment for
regression tests. The next verion will have bin/owmemcached.

Thank you for your reply.

I have used the OW before. When will the memcached OW be published?.

And how can I get some materials related to memcached OW?

It's in the CVS repository and there is no document yet.
