OUI set to a VMware #54

The randomization protocol automatically sets the first three hexadecimal values the same every time (00:05:69). This is not particularly random, and tells any device that you are either operating a VMware virtual machine or are using this software to spoof your MAC. I read through the source code and saw that you chose this range because it would have a very low chance of colliding with another device on the network (one in 16.7 million for any other random VMware MAC), however I would recommend throwing in some code to switch between a couple of different possible VM designations: 00:50:56, 00-0C-29 for manually assigned VMware MACs 00:16:3E for Xen VMs 00-03-FF Microsoft Hyper-V, Virtual Server, Virtual PC 00-1C-42 Parallells 00-0F-4B Virtual Iron 4 08-00-27 Sun Virtual Box

Doing this will increase the anonymity without greatly increasing the risk of collision.
