hmmm, well, what you are talking about is the "MAC address", if I'm not 
wrong, and it belongs to "every" etherner board. but it is something 
"below" IP, IP sits on top of MAC address and is more used (in internet 
times).
I'd swear I got an IP address for my mobile phone, on the PC, when 
they're connected together. Or better, the bluetooth adapter for PC 
showed up in Network adapters, and got an IP address or could even be 
assgined one.

try IPCONFIG /ALL at CMD prompt, and you will see both MAC address and 
IP address.

This is what I was thinking, it must be some kind of very new feature, 
probably available only in XP and, as for the compiler, in latest 
version of Visual Studio/.NET

I see.

never been into Java so if you find a solution over there it'll be good 
for you!
