Social Profiling Widget and Site

Please have a look at this solution: [login to view URL] As you can see this is a widget that works off iframes. I want to create a site that gives users the option to create such a widget. This widget will sit on each users page i.e. [login to view URL] The widget should also be displayed using .js javascript code anywhere else on the web that a user may want to display i.e. blog. I simply want all of the features there and an addon would be that it can be dragged around the page and placed anywhere. I want you to look at [login to view URL] user interface to get an idea of how I want the backend of the site to look for a user to set up. Everything should be customizable include colours. The rotating image solution should be allowed also so a user can put up images that are rotating. Since it is a way to display social network sites. I want to give the user an option to create a custom 'micro business card' i.e. upload a picture, provide some text as the first information that a vistor sees. Users can upload an image the sits around this picture and text like for [login to view URL] backgrounds. If you can do this in Joomla 1.5 it would be a bonus
