BuddyMobile + Buddystream and Widget In Footer.

So I Am using buddymobile and I wanted to get a widget in the footer. It's a widget for this plugin

http://wordpress.org/plugins/buddystream/

Now I know for the average theme you register a widget then easily put it in the footer. The thing is buddymobile has no backend so if I register a widget it still doesn't matter because the widget wont show up in any backend.

How can I get the buddystream widget in the footer of my buddymobile plugin/theme.
