Getting a NIC's ID

["Chip Dunning" <cdunning@xxxxxxxxxxxx>]

Does anyone know how to get the UID from a network card. Because of its 
uniqueness we are using the NetworkID as a singular factor for identifying 
hardware. The previous programmer did a system call and grep'd on the result - 
I am hopeful that there is a code-based method of getting this information.
