Show MAC address and IP Address in "Additional Info"

As a network administrator, I use System Explorer to tune the computers on my network.  It would be very nice if I could see some other info in "Additional Info":

• MAC Address
• IP Address (ipv4 at least)

This is the main thing I would like to see, and would use alot.

Some other information that would be nice would be:

• Motherboard information (processor, etc.)
• It would also be nice if I could use System Explorer to tell me about the user's RAM configuration (kind of like Speccy and SIW can do).
