Photo proofing plugin
I could really use a photo proofing plugin and I know there is a lot of demand for this after searching for a long time. It should be possible for the photographers clients to log in and pick there favorites from a photo session and leave comments for the retoucher. The possibility to pay for a selection to print or download the files.

can you please show a site (wordpress or without wordpress is fine) where they have such feature ??
That will give a more clear picture of what you are looking for.
