SharePoint OneDrive file sync issues when users open the same file

ChrisWebbTech  Hi guys. Sorry to open up this thread again, but it seems as close to issue i am having, that i have found. I want users to sync company SharePoint files using OneDrive, but i don't want all data to remain on PC. Data protection more than anything else in case PC is lost or stolen. I like files to be cloud only until opened. Let it download and then, go back to cloud only. Much like how ZeeDrive works.  We have used ZeeDrive with other clients, but there is still support involved with ZeeDrive, that we want to avoid. Also, we want to move away from the mapped drive methodology. Files on-demand keeps a local copy and it appears its a manual process to 'free space'. However, there's no server to push out GPO. Office 365 deployment. Any advice would be appreciated.
