Well, for those of you who have no idea what I am talking about, Hamachi lets you play LAN games over the internet by allowing you to join virtual LANs!

It's pretty sweet. I have used several others, but this is by far the best.
Here are just a fre "fun things" you can do with it:
Play games that are "less than legal"
Share files over LAN
Share iTunes music (and use MyTunes to
really share iTunes music)
Play games with your internet friends that don't have an internet gameplay mode.
It also supports chat!
anyway, I thought maybe someone here may be looking for something like this, so there ya go!
The download is free, give it a try!
