Quickly create a simple network using the superb LogMeIn Hamachi

Networking with another Windows machine isn't always easy. It's made much more difficult if the computer you want to join to your network is situated outside of your home. For instance, there's no reason why you couldn't join forces with a few friends from your neighbourhood and create your own network, which is accessible by all machines across this network. There are major advantages if you want to share files, swap important data or play network games. However, getting start is the hardest part.

LogMeIn Hamachi 1.0.3 is a free (for non-commercial use only) zero-configuration networking tool that will enable you to connect computers in your home or in a radius, to your existing network. It's based on P2P technology and will work across operating systems, so you can as easily connect a Mac to a PC as two PCs.
