I wonder what's stopping someone from configuring a server to automatically create a copy of the uploaded images, size them to a more manageable size (say 800 x 480 pixels or so, so that they would fit nicely on an iPhone screen), then allow iPhone users to get them 'real time' via RSS feed?
Something like this would be nice for wedding or other event photographers. Anyone could view the semi real-time images from the wedding using their iPhone.
Of course, they would be getting all the bad and unedited shots, too
