Right now the integration between SmugMug and PM is pretty basic, just FTP. With the catalog coming, all my metadata will presumably be centralized in the catalog.
Now I need a cloud solution and I don't like Photoshop.com. I'd like to be able to sync data from my PM catalog with my photos in SmugMug. In conjunction with SmugMug's smart folders I could reconfigure, reorganize and change my presentations on SmugMug just by changing the metadata in PM. Very powerful.
It seems like a natural alliance, or at least a nice piece of functionality, that would be beneficial to both companies. Wishful thinking?
