[Zope] Remote scripting?

Hello, Remote Scripting means: calling server-side code from a client-side script without causing the active page to be reloaded. (for more information see http://www.ashleyit.com/rs/) The website mentioned above contains an HTML page which contains two comboboxes. The choices offered in the second combobox are calculated on the server, depending on the choice that the user makes in the first combobox. The values of the second combobox are retrieved from the server by communicating with a java-servlet, and all this is done without reloading the active page. (using DHTML, ofcourse). Has anyone done such a thing with Zope, in stead of a java-servlet? Cheers, René Olsthoorn, Mediasystemen, The Netherlands.
