Possible to create a Sign in with Ghost plugin for Discourse?

Darn, alright, I hadn’t realised that unofficial & custom plugins were only available for Enterprise plans. I see what you mean then when you say that “The burden would shift from self hosting a relatively simple Ghost-add on, to self-hosting Discourse.” Problem is, while self-hosting the “simple add-on” may be too troublesome for the tech-challenged, some may want the reassurance that nothing is in their hands and that all operations are safe in the hands of the more competent.

That all being so @pmusaraj, seeing how custom plugins are available only for Enterprise plans, is it effectively the case that plugin-wise the only options are on the “extremes” – either self-hosting or Enterprise? I totally understand why custom plugins wouldn’t be available for Starter plans as Discourse needs to make some money to maintain itself, but might there be some middle-path here? Or alternatively, might there still be some other route besides a plugin or “configuring Ghost as an identity provider” that hasn’t been addressed?
