As you may already know, Mac Changer is an open-source tool for viewing and changing the MAC address of your network interface card. Among others, it permits you to specify a certain MAC or set a random one, set a MAC of another vendor or the same vendor and display a vendor list of macs.
We use such a tool to clone the MAC of PC, in the dorm house, to permit others that are not in the MAC list to access the internet.
The latest version available Mac Changer 1.7.0, which has been recently released.
