In private email I sent you a reference to a paper that describes
trampolining in detail and its connection to CPS.  As for seeing an
interpreter in CPS itself, you might find it worthwhile to peruse the
relevant chapter of my PL book, PLAI (www.plai.org), or the superior
EoPL (www.google.com).

Finally, though for a long time I used to think of event-driven
programs as being "merely CPS", I have now come to see them as
something different -- as what (for lack of a better name) I call
"event-style".  It's not quite the same thing at all.
