uhmm... netstat?
if the protocol is supported the kernel, (eg via a socket() domain)
then netstat should support it too and display it.
if the kernel doesn't support it, then the app must be using a raw
socket, and tools that query the kernel will only ever find out it's
a 'raw' socket.
only way then to find out is to snoop on the traffic itself ->
tcpdump.
so the answer is "netstat"
