You could decorate the social module that you are using and add additional fields to the admin to control these extra buttons. I think that we might need a social module that allows any number of social connections, with the ability to add and delete them.

Creating your own social module or modifying the existing one would be hard. I would suggest simply adding a template via the custom skin module, or your own custom module, and using that to add the social buttons.
