organic groups? Flagged?

I'm a drupal 7 newbie, so please excuse me if I'm getting something very wrong. As I understand it, this module is trying to make files just like other entity object in drupal 7, which from my drupal 6 experience, is a sort of like making files true content types (in drupal 6).

However, It's not clear how, with the current code features, I would integrate this with Organic Groups. In og, when you edit content types, you can specify on the content type edit screens whether the type can be a group post or not. How would I do the equivalent with file_entity 2.0 branch?

Additionally, I use the flag module (http://drupal.org/project/flag). It also has the ability to specify which content types can be flagged or not. Of course I don't see an option for enabling flagging file entities, just regular content types. I'll take up that issue on the flag support page, but I was wondering if anything needs to be done here as well to support that kind of feature, or if it will always be out of scope?

thanks,
