TeamViewer

TeamViewer is a free tool that makes it incredibly easy to set and use a VPN connection; a Virtual Private Network that lets you take complete control of another PC from your own computer, whether they're separated by a soda can or a continent (and as long as both machines are running TeamViewer). It enables two-way connections in which users can flip control back and forth. TeamViewer also lets you hold virtual meetings with multiple participants (again, they all must have TeamViewer installed). With a name like TeamViewer, you'd expect it to be an enterprise-ready tool, and you'd be right: TeamViewer's robust simplicity is what happens when multiple users of vastly different skills need to use software. After a while, the bugs get squashed pretty firmly. But TeamViewer is free to non-commercial users. That means you can use it to access your work and home PCs remotely, of course. But you can also install it on your mom's PC (for example) and provide tech support from home.
