Hi, thanks for the response!

When I first read the features, I assumed the Facebook/Hangouts and XMPP were essentially 3 different modules, which would probably make extending it to third party plugins fairly easy. But I realised that all of the services are XMPP at the moment, and therefore I suppose this would mean adding lots more abstraction to internal APIs and stuff.

I've heard about issues with sandboxing and plugins before, but as far as I can tell they are mostly for when plugins need access to the filesystem, as they have a different bundle ID and therefore don't get permissions from the main application? I might be completely wrong there though. As long as the plugins for Flamingo don't need filesystem access, or other privileged access, I would have thought it would be fine. RapidWeaver, for example, has a large plugin community, but is distributed on the App Store.
