You can't, but I hope to get the first non-prototype implementation
done next month.

At least initially, this will bypass security, so authentication is not an issue.

If we tried to deal with security issues, things would got a lot more
complicated.

That proposal has some problems wrt the goals of file-system synchronization.

1. RepresentingObjectsOnTheFilesystem doesn't try to be lossless.  It's critical
    for file system synchronization to have a lossless representation.

2. The representation isn't flexible enough to represent all object data.

3. The RepresentingObjectsOnTheFilesystem doesn't seem to deal with potential name
    conflicts between data and resource/meta-data files.

4. The RepresentingObjectsOnTheFilesystem proposal mizes data and meta-data.
