Functionality

Pete,
Generally, what your video shows is possible... plus more. I'll try to cover most things quickly though:
1) When a user logs in with their social network credentials, their most recent status will be imported. That works for FB, Twitter, Google+ and LinkedIn.
2) When a user posts a status in JomSocial, if it's set to "Public", that will be posted to their Facebook account. We're planning an update that will also post that status to other (configurable) networks, excluding Google+. Google+ has a 'read-only' API, so we can't post anything to it.
3) In addition to just status updates, we have "Open Graph Actions". The best demo of that, if you haven't seen it, is our JomSocial integration video:

You can learn more about Open Graph and how to configure it in the following links:
www.sourcecoast.com/jfbconnect/docs/open-graph/actions/
Specifically, there's an example configuration for auto-posting new image uploads into JomSocial to Facebook:

I hope that helps explain some of the features we support. Should you have any other questions or clarifications, just let me know.

Thanks,
Alex
