Hi
Perhaps someone has suggested this before.
I'd think many of my colleagues would welcome the idea of a simple client image proofing system as part of paid version of Dropbox. It'd help you convert non paying cutomers to paying customers!
I'd upload low res images to DB and send invitation to clients. They could "star rate" the images and then send in an order.
Lets say they want 10 images in a photo book.
2 images as 8x10 prints and 2 other as 4x6, Canvas, custom print etc.
They'd just say in comment.
