Well, look at the Image Target question type that I linked to. That uses Javascript to cope with positioning the marker on the client side, but the rest of the code is PHP on the server.

The other approach is to make a question type that allows arbitrary Javascript or Flash on the client side, which does all the processing, and then does the minimal amount of work on the server side. That would also be a question type worth having.

This sort of discussion more often happens in the quiz forum: http://moodle.org/mod/forum/view.php?f=121
