Versioning File System for FreeBSD?

[cpghost]

Hi,

is there anybody working on a versioning file system for FreeBSD
right now?

Maybe something like what's discussed here?
  http://www.pdl.cmu.edu/PDL-FTP/Secure/FAST03_abs.html

I don't care if it is native or a layer, geom-ified, fuse-based,
or even if it uses subversion as its backend, as long as it
provides some kind of transparent versioning.

Anything like that in the works?

Thanks,
-cpghost.
