Hamachi, the easy to use Virtual Private Network application, was updated to version 2 (Hamachi²), bringing a lot of improvements, the most notable being web-based management which can be used to create networks on demand through your LogMeIn account. Another important change is the redesigned GUI.
How Hamachi works:
You'll create a virtual network one time, then join all your devices to that network using a secure key. Hamachi installs a virtual Ethernet adapter on your computer, and uses this to communicate with your virtual network. After signing in, there's really nothing left to do - Hamachi's zero-configuration standard means you shouldn't need to adjust your router or firewall settings at all.

Please note that Hamachi is only free for non-commercial use.
