I did an interactive DVD that contained multiple-choice quiz questions on each segment. Something like seven segments, each with two questions, each question with 4 possible answers, the bad answers branched to a "sorry, this is why you are wrong/try again" loop, the correct answers would congratulate and reinforce your choice with added info then send you on to the next question. Shooting took something like 3 days, one for all the host standups, two for the play-acted scenarios in all their permutations. The raw edit to boil down finished segments took me roughly a week. The authoring step in DVDsp took around 14 hours as I recall. I'll try to upload a picture of the resulting logic map from that project.
There is purpose-built quizware out there that runs in HTML as well as flash, and offers things like automatic scoring a grading, etc..
If you want something more modest, you can build the quiz yourself in powerpoint and use canned buttons in there commanding jumps to certain slides to direct the same kind of interactivity as the DVD thing I discussed above. And, while the code you get is nothing to be proud of, you can have powerpoint automatically turn the presentation into HTML and you can then run it offline using a browser or post it on the company intra-net.
