Hey, you need more than VNC that just lets you take control of a remote computer. Gotta have a VPN gateway so you can securely access the whole local network. With a VPN connection I can log into servers, and use Remote Desktop instead of just a VNC to control computers. Also using the Personal Hot Spot on my iPhone i can work from anywhere I have cell signal.
And they think I work from home.
Lately we are moving towards Skype to handle help desk support. But the user has to be present. With remote desktop the users computer only has to be on to monkey with settings and install software.
