We've done a number of demos of that type using either remote desktop or LogMeIn using Access and actually let them play with the prototype and make suggestions, and it worked pretty well. We had a single PC dedicated to that sort of thing. One of the challenges in your case is to make the Access prototype have the look and feel of a web app - it's very easy to implement functions in Access that are either very difficult or impossible to implement in a web app.
