It's recommended that the ui. namespace is only used for official jquery widgets:
"All jQuery UI widgets exist in the $.ui namespace, which is reserved for official widgets, so make sure you change this to something unique. Namespaces are used internally for organizational purposes; they do not allow you to create multiple widgets with the same name." - http://www.erichynds.com/jquery/tips-for-developing-jquery-ui-widgets/
"The ui namespace is reserved for official jQuery UI plugins
Just because you're using the widget factory doesn't mean you have to use ui
We'd kinda prefer if you didn't :)" - http://ajpiano.com/widgetfactory/#slide22
