You can't do this and keep it tamper-proof with JavaScript/PHP. No matter 
what, anyone with an IQ above that of a tree stump could play with the POST 

I think the only way to do this and keep it tamper proof would be a Java 
applet. If memory serves, you can have record the time on the server, and 
have each answer sent as it is answered.

If you had a web site that posted forms to the server after every answer, the 
transmission time would have a big effect. No, Java is the way to go.
