Joel, I've been discussing this with the author of The Physics Classroom. He
has been thinking for a while of dropping the internal/external wording
and addng a presentation and examples of "systems". He is generally responsive
to making corrections and improvements to the site when people contact him.
Of course, as he has five or six classes to teach, exams to give, etc., changes
won't be immediate.
