Share Stream video with external users

I thought when Stream was announced last year it was supposed to be a new "YouTube" like offering--allowing users to share video with others, even if not part of your org, or an authenticated external user in O365. I also thought it would "integrate" with O365 Video--which we now use frequently? (or maybe the term is O365 video would fold into Stream?)

We love O365 video, and we produce much content--mostly learning videos for staff, and, as another user mentioned, the uploading of recorded Skype for Business sessions.

We need to have the ability to show this learning content to both external users who have been invited to our SharePoint sites, as well as a broader audience that we'd sometimes like to just be able to access anonymously through a distributed link. We'd also like the ability to toggle the anonymous access on/off if possible. Also, O365 video has some limitations, i/m/o, on file names, and how the descriptions are displayed, etc. Also, we should be able to tag the videos with metadata we already maintain within the O365 system, have "like" or "rating" capability, and display number of views. I suppose a "comments" feature would be helpful as long as they could be turned on/off.

So far, we've not been able to do much of that with O365 Video, and we were hoping Stream would be the answer. Can you please update?
