I'm working on a more detailed manual for font handling in context (but as we sometimes go beyond what opentype provides it will be somewhat specialized). > 5) Any of 3 and 4 in the source distribution?

One of the things that context does is normalize and optimize the raw font data as provided by the loader. One can always print the tables (as used in context, using the table serializer). The structure used is rather stable. There are also hooks to kick in extra code (for instance, context adds additional features.)
