How to use jQuery in an extension

Question

Hi. This is a tough nut to crack: Is it possible to use jQuery in a Dreamweaver extension? These extensions use the following syntax to reference the extension and the actual document which the extension will modify:

document.forms[0].elements[1]   // refers to the extension file's form element

var dom = dw.getDocumentDOM();  // gets the DOM of the current document 
var firstImg = dom.images[0]; 
firstImg.src = "myImages.gif";

You can have SCRIPT library tags in an extension file (which is a *.htm file), so we should be able to include the jQuery library for use. The trick is how to reference the current document DOM and the extension's DOM to get a handle on various objects in the extension and the current doc. Anyone have any thoughts or solutions? Thanks :)
