That's pretty much it - but it  assumes (1) the device is actually using 
an IP address, and (2) it's on the same subnet, otherwise ping won't 
help.  There's a utility called arping (like ping, but for MAC 
addresses) but it won't tell you the IP address.   The only other 
possibility I can think of is if it uses DHCP (or more likely bootp) to 
try to get an address, you could snoop on that.
