I had not really explicitly considered that possibility in working on this. I suppose this is a step closer to that, but there are still some pieces that we would need to add. What kind of things did you have in mind?
There's lots of commercially licensed, self-hosted software (blog, forum, ecommerce etc) and hosted-as-a-service (wordpress.com, discourse.org, duelapp.com etc) etc that would be applicable.
Enabling that by API or in general would be awesome.
