OK, so libpcap has "pcap_findalldevs()", so that's probably what's being 
used to find the network interfaces.  Just out of curiosity , what does 
"tcpdump -D" (tcpdump, not tethereal) print?

OK, no IP address, so it won't show up in SIOCGIFCONF (the primary 
mechanism used by libpcap on Linux if "getifaddrs()" isn't present).

What does "cat /proc/net/dev" print?
