Sharing InDesign Library files (*.indl) with others on my team.

I spoke with InDesign "folks" at the recent Adobe MAX conference in Miami, FL, and they suggested using the CC Library to share these files, but they are not allowed to be posted. This was the suggestion given to me at the conference/convention.

I need to be able to share access to these files (I have several libraries), but if I'm using InDesign, others can't even open them, much less get the content within.
