pretty cool.  some thoughts:
 - should lookup IP addresses
 - should lookup ports using getservent
 - add a flag to enable that look up logic since it'll probably be too slow 
for default behavior

i don't think we want to use that model.  the /proc net filesystem is known to 
have limitations.  instead i think we should do what iproute2's ss tool does 
-- use netlink sockets.
