Since we haven't yet tried to push ploop upstream yet its git repo is 
not available (and internally we use something like stgit but based on 
CVS and lots of shell code and *.patch files).

A patch (or, better, a patchset) is fine.

I suggest you start with using --layout option, introduce a new CT 
layout (say 'device'... can't think of any good name right now) and 
patch the mount/umount code to support it. VE_PRIVATE can be a block 
device name in that case I guess, VE_ROOT remains the same (ie mount point).
