Your first stop should be the latest revision of the proposal by Vandevoorde [1]. He also presented the paper at C++Now! [2]. Do answer some of your questions: Instead of compiling directly to object files/libraries and distributing headers with them, you will be able to distribute modules files. Those will be preprocessed and already be transformed to some vendor specific format. Templates require some (actually a lot) processing before they can be instantiated. This can be done without knowing any of the types used for instantiation and this can be used to speed-up compilation.
