Flag file entities in drupal 7, or flag entities in general?

I've recently switched over to using the file_entity module for handling files instead of the typical route of creating a content type and adding a file field to it.

When I had custom content type with a file field on it, I could flag the content type just fine. However, now with the media module and the file_entity module, my 'files' are now entities and not content types. Hence, I cna;t flag them anymore, as far as I can tell.

Is there any plan on extending flag to flag entitites instead of just content types? Does this exist already as a another module? An obvious benefit would be that then flagging would work identically across all entity bundles, so flagging users, or comments, or files would all come 'for free'.

Any help or comments would be appreciated,
