I think the only problem here is that we don't think to go looking for a solution. It will have to land in our lap to get used. And, I don't know that I'd pay for a solution unless it worked like magic. Lastly, I'd want it to be a desktop solution that I only pay for once. I have enough recurring payments in my life, I don't need one to manage my photos too.

All important points I'll keep in mind. I'm not thinking too much about business models yet, but patterns of adoption are important.
