liveDFS - a dedup filesystem based on ext3 for vm images

[Moriah]

Has anybody tried out liveDFS? It is a dedup filesystem based on ext3 optimized for smaller systems (read "*NOT* enterprise level) aimed at virtual machine images. I want to try it out, but thought I would ask if anyone else had already done so, and what their result was. Their webpage is at:

----- EDIT 2013_08_02 -----

I have fetched the tarball for liveDFS, as well as a couple of newer versions called ScaleDFS and RevDFS. Right now, I am fiddling with ScaleDFS. I have gotten it to compile, load, and create and mount the dedup filesystem, but after I write to the filesystem, and cannot unmount it.

I have put together a bug report and emailed the author(s), and will report back when I get a response.
