I know, it's hard to draw a nice objective line in the sand. A general-purpose browser with a new UI, for example, ought to be allowed without requiring permission from anyone.
On the other hand, what if I write an iOS app just for getting answers from Wolfram|Alpha that displays the content using Webkit? I could certainly understand Wolfram arguing this kind of thing requires permission.
I'm curious about DuckDuckGo's use of Wolfram|Alpha content. There's an example of framing content and deep linking together. I assume they have permission or an army of lawyers?
