I am in the process of setting up a home theater system connected to my home network when i noticed that my Sony BluRau has an ethernet port. I'm curious as to what this feature adds to the overall functionality of the device, my home theater, and my home network? For example, can I play a movie on the bluray and watch it on a PC on my network?, Can I use the bluray to add a movie to my Plex media center (with all due respect to copyright issues)? Not sure what to do with this feature.
