It's a great money making opportunity for Micro$oft. Think of future versions with DRM built in!
I shudder to think of DRM being applied to still photos, but the concept is nothing new. Film photographers have used all kinds of techniques to keep proofs from being stored or copied.
Hight res digital images now have watermarks, some visible, unless you buy the rights. The companies that make watermarking software charge a fee per image. If Microsoft gets into this business, it will just be another competetor.
