OK, it’s got an Ethernet jack and a Web server on one end. What’s on the other end? If I were designing a clothes dryer or coffee machine and wanted to Internet-enable it, how would I hook up the signals from the control panel to the jack? Is there some standard bus or serial protocol that appliance manufacturers use for their onboard computers?
But, if you're really interested in internet-enabling a new product, you'd likely be better off selecting a microcontroller with built-in Ethernet (or an Arduino with Ethernet shield, if prototyping). In my experience, products like the XPort were better for manufacturers looking to internet-enable a legacy device with a free serial port.
