This may have already been asked elsewhere, but have you considered having a disqus type feature for embedding discourse topics into other websites?
I could see an application for platforms like Loomio.org that want to focus on other functionality but also need forums.
I’ve been seeing disqus in the unlikeliest of places, from thinkful curriculum pages to idealist.org. They offer this integration as a feature for websites - I’d rather use discourse! Engage Your Audience
