Ask your users if they'd mind you including VigLink or something like it in your widget. It monetizes outbound hyperlinks that are already on the page by rewriting them to be affiliate links when there's a relevant program. It doesn't change the behavior of the site and doesn't overwrite any that are already affiliated. If your users value what you're doing they shouldn't mind you harnessing a little potential that they're leaving on the table. I'd definitely recommend disclosing it though - people will get pissed if you do it silently. Upside is it's totally fire and forget.
