If you are looking for additional material, I might be able to do an introduction to CMake (following the Xcode presentation) if there is any interest. This might dovetail nicely with the Xcode presentation. For Cocoaheads regulars, this will probably be new material, and for new people brought in by the iPhone SDK, the cross-platform focus of CMake might be of interest to them if they are considering reusing model code from their previous platforms. Please let me know so I can prepare something if I need to.
