Hamachi (VPN, free)

With more and more folks running home servers or simply wanting to access their documents or stream their iTunes library across computers connected only via the loose strands of the internet, Hamachi's free Virtual Private Networking client is an absolute savior. While Hamachi is more for us geeks than Average Joe, I don't go on a business trip or walk down to the coffee shop without secure access to my home computer with Hamachi. Here's more on how to create your own virtual private network with Hamachi. Note: Not sure if Hamachi was born in 2006, but LogMeIn bought it this past year, when it came onto our radars.
