I'm looking for some tool that can allow automatic bi-directional syncing between Picasa Web / Google Plus and a desktop photos folder.
The use case is of alternating between managing photos locally and online, so that if I e.g. decide to delete a crappy photo using the web site, the deletion propagates to the desktop.
I'm open for all directions, e.g. it could have been great if there was some tool that allowed mounting the Picasa Web albums locally (analogous to say s3fs for Amazon S3) so that I can use rsync.
