That sounds good, I think freemium is the way to go. When I first found face.com I thought to myself that I would have no problem paying for their service. I am definitely interested in your project. And I think developing in the open will be hugely helpful. For my purposes though the REST API is what's more useful since my problem is not connectivity or bandwidth but processing power. Right now my software is running on a Raspberry Pi which can just barely run motion for capturing the pictures, I would need a real computer to run a full OpenCV install. That is why the face.com API suited my needs so well. Are you planning on offering facial recognition along with the face detection or just focusing on face detection for now?
