Connect to an External Workspace

I need the ability to integrate my work spaces with customers and clients so that they can interact with my visualizations from their own workspace.
1) They have their own Power BI implementation or Office 365.
2) They are authenticated against their IdP.
3) They see my workspace that I have shared in their environment (no need for bookmarking URLs)
4) Their IdP admin can manage roles (consume, modify, etc.)
5) Their IdP admin adds new users and removes old users.
6) I manage at the external client level thresholds for usage and consumption (e.g. no more than x refreshes per day, no more than x GB per month, user may / may not make duplicates or new reports, etc.)
