I found a microcontroller with ethernet, tcp/ip embedded into the silicon.  $4
There is a rabbit for about $30 that will do similar things.  

I want this thing to be $20 and as small as a jump drive.

$200: https://store.gumstix.com/index.php/products/283/
or

GPIO ports are easy to program against.

  Yeah, too big.  Physically.  Looking for a single port device, hopefully the

  Lots of folks have connected a relay to an ethernet port to loop it back.  
When the relay is open, the connection goes away.  

  I am looking for a way to do some centralized polling of ports like that.  I 
don’t want to have to build some kind of small ardueno board and burn an IP for 
each one.  But I can’t think of a way around using an IP unless the device, 
such as a managed switch can do an snmp trap for each port.  

  Maybe it will become a product if it doesn’t exist.  Telemetry on a stick.  
Two terminals for a contact closure.  POE powering.  Pollable and trap sending. 
    Hopefully something like this already exists?
