My proposal was to write a FUSE (that is, file system in userspace) 
driver because:

    * davfs2 doesn't work (at least at the moment) with ownCloud
    * you need root privileges to mount a share
    * from what I've read, it doesn't do read-ahead

And if using a regular daemon for synchronizing your home directory 
you'd probably get lots of conflicts because you won't be able to tell 
apps "wait before I check if that file already exists", etc.

I'd say a python script running under the user's account isn't either.

Shouldn't the server do that, especially as the project features say it 
needs to get rid of older revisions if it is running out of space?
