Cool idea coming from Minolta. Using Minolta Messenger, a photographer can annotate a photo with text, that get's stashed in the image itself. Then the image can be e-mailed to a friend. A trial version of Messenger can be attached to the image, said version reverting to reading only after 14 days.
Sounds like a great idea just from it's utility, but even cooler from a viral marketing perspective. Microsoft is probably kicking themselves.
Wonder how long it will take for someone to reverse engineer it and then get sued by Minolta under the DMCA though?
