Agreed. It's generally a bad idea to build your entire product around a missing feature in the Big Guy's thing. The surprising thing about Amazon, however, is that they've gone out of their way to be the exception to that rule over the last 4 years. JungleDisk was the posterchild for "business that will only last until Amazon incorporates their product as a feature", and yet it continued to survive as Amazon released infrastructure product after infrastructure product. And in the few cases where they did move into a space where somebody had built something, they did it delicately and cooperatively. They really were the Good Guy. I'm hoping that this was just the one space that so obviously needed filling from a Company Strategy perspective that they're making an exception in this case. They've built up a lot of goodwill. It'd be a shame to see it squandered.
