Thanks for the links, guys, I will look into them. I'm not worried about Apple for two reasons: - The layout engine I have prototyped (there is no binding, only layout proper) operates on native iPhone controls, i.e. it does not create a new abstraction layer on top of UIKit but rather extends it form the side with smart sizing and positioning. I think it's very important to avoid creating leaky abstractions and I plan to keep doing things this way. In other words the layout description describes layout of native UIKit controls, not some abstract presentation of data. - I'm no Adobe, and I'm not likely to attract attention to myself.
