I just noticed this http://groups.google.com/group/sage-devel/browse_thread/thread/16fc3c4cb4020728 recent thread referencing http://wiki.sagemath.org/days7/coercion, which addresses alot of the things we had questions about. It's good to see this restructuring happening, and all the good energy around this project!
