Somewhat off topic... Using some hardware related information such as NIC
info will either break high availability solutions or require such hacks as
kernel modifications to allow software setting of the MAC address. Take a
look at FlexLM (used to manage Matlab licenses) as an example of how *not* to
design software protection.
