This will require some trust from both parties, though, as you can technically access their computer at anytime.TeamViewer 14 is the latest portable version of the popular remote access/control program. No IDs or passwords have to be given, you can access an older version with newer versions, and I believe you can even remotely update the TeamViewer Host, if I recall correctly. Otherwise, you can download the normal TeamViewer 11 full version and the TeamViewer Portable for TeamViewer 10. Therefor you can just have your TeamViewer 11 on your device and connect both to the TeamViewer 10 and TeamViewer 11 versions. If you are only talking about outgoing connections: TeamViewer is downwards compatible.
