Hamachi is a vpn technology. You can run this software on several machines and create a private network that runs on top of the existing networking stuff. VNC uses a TCP connection between machines. As such, most firewalls block incoming traffic unless there is an established session through the firewall( some will block anyway).
Back to Hamachi. The free accounts are what you get when you download the software. It will allow you to create multiple networks and attach up to 16 computers to that network. Hamachi uses IPSEC technology with UDP packets. This means that most stateful packet inspection firewalls will allow this data through. The end machines decode the IPSEC packets and hand the data off to another virtual network interface inside the computer to act as a normal networking interface. The reason I mention any of this is VNC is a security risk if used across the internet or you open a firewall port just to allow you to have access. The VNC passwords are not totally in the clear like ftp but with a little work with ethereal you can get it. Also once a session is established someone could snoop the session and watch what is being done. With a VPN, none of this data exists on the internet for someone to use.
