449412 In context editing

I am trying to build a website that I can edit in context. You can see an example here [login to view URL] If you dbl click text it will turn into a text area. You can make edits and see them but it dosn't save. refresh the page and the old values are there. So I need the files to to edited on the click of a save button. (that way you can edit the entire page and save it at once. I also want to have a way to add elements. My goal is to have all these functions be added to a basic xhtml page. So I can build sites for people and give them the ability to edit them. I want to build the frame (header menu footer) and then the body kinda as posts that I customize. In the end I would build the page, and several post templates (still just xhtml and css) The saving part is my biggest issue at the moment. clicking the image shows a upload box that needs to upload the file and display the photo.
