Anyone ever try this? http://www.hamachi.cc/
With Hamachi you can organize two or more computers with an Internet connection into their own virtual network for direct secure communication.
Think - LAN over the Internet.
Think - Zero-configuration VPN.
Think - Secure peer-to-peer.
Access computers remotely. Use Windows File Sharing. Play LAN games. Run private Web or FTP servers. Communicate directly. Stay connected.
Might be a great way for some of us sharing files to do it in a simpler manner than tyring ftp's or in some cases **cough** mailing cd's to each other.
