Ability to share over facebook, or provide a link for editing/viewing

I agree. Not all of our consumers will need to have access to all models. In our organization, we would like to share the output of progress with our business users, but have to go through the trouble of exporting the diagrams and saving them to a common area each time we change them.
In a perfect world, we would be able to send them a read-only URL which would display the progress or latest version of the diagram. One company that has a comparable feature to this is a roadmap software called roadmunk (roadmunk.com)
