JSMX and Lightbox Modal

I have spent the last few days working on some excellent functionality using JSMX's light weight AJAX utility combined with Lightbox modal dialog boxes. Combining the two gives you the ability to simulate a desktop application via a web page. Albeit, somewhat tricky at first to get a handle on modal, and the pages you call into the modal become part of the current document object model. So, to run forms and additional js validation, I created a modal wrapper which directs the modal window to the src destination in an iframe to handle any forms. Pretty cool stuff.. I'd like to find the time to experiment with other modal, ajax frameworks.
