I'm sure that most people out there are similar to myself and have used Teamviewer on the blurry edges of commercial use.
It's not commercial use if you just can't be bothered to go into work to restart a server or kick off yet another render at 2am, can it?
Sadly I'd more they likely say so, but step up google and there free for All Chrome Remote Desktop.
Obviously not as slick as Teamviewer, but hey, it's free.
Will post more as I use more in place of Teamviewer.
