It's not so hard really. Just grab a plugin that already gives settings per blog and copy how it does it. Basically it's just a matter of using get_widget_param_definitions instead of GetDefaultSettings but personally I'm into using both. I figure whoever owns the blog should have the option of saying if one set of settings covers all blogs or if each blog should be able to set settings on it's own.
But anyway grab a plugin that gives per-blog control and use it as a template for what you want to do.
