If you’ve ever used virtual network computing (VNC) to remote control into a distant computer, you know it can be a hassle: the controllee (person on the other end) can never quite get all the port settings correct and the whole thing takes more time than it’s worth.

Now, there’s a solution called UltraVNC SingleClick. You email a program to the controllee and they set it up with — duh — a single click. No more hassle!
