Some common settings, such as pitch, post settings, etc. could be adjusted via solenoids, etc. and therefore tournaments across different machines in different locations could be fairer and more standardized. Webcam integration would be fairly easy to integrate and could provide a more interactive experience. I am amazed that standard network (either Wi-Fi or Ethernet) is not part of standard machines these days. I think it would be a good way to expand the market though, since the next generation is a connected one.
