1. What are your future OS plans? Will you be providing Server 2012R2 or Server 2016 (when it is released)?
2. How do you control access to a particular instance? How do I know a Frame engineer isn't shadowing my session?
3. How is instance integrity maintained? How do I know a rouge Frame engineer hasn't installed a key logger in the base image?
4. Do you plan to add other cloud storage providers (e.g. OneDrive)?
