Karl according to this, the user doen't have to actually install
Teamviewer, but instead can choose to just 'Run' it, see:

I've not tried it, yet, and the link appears to be dated, so you might
want to test before pushing out to your remote user. On the other hand,
the remote user might be better off just installing Teamviewer - TV
provides VPN, encrypted chat, video & file transfer etc. And you can
tell when the user has TV'ed into your system by the TV seeion tab.

so the same problem as Synergy. There are a dozen other
