I just realized that i have completely ignored writing about data connectivity through webservices all the while; It was too obvious a method, may be thats why i missed it. I will ensure that I come up with a prototype and a how to do doc, soon.

But most importantly i missed out mentioning Widgets in all my blogs. These plugin dashboards can be seen as your mobile apps/widgets that you drag in your screen and use; what i have been explaining all through out is that u can embed these dashboards inside your web application but forgot to mention that these can also be seen as independent widgets that can automatically connect to datasources and give you interactive representation.

following are some of the links where I have shared my thoughts about the Plugin Dashboards (sans webservice and widgets).
