Scenario:
A home network with a cable line running into the house to a hub the proceeds to send the signal out via in-house ethernet wiring.

I need to pay for each additional IP address for use with the cable connection (3 total - I have roommates). There are additional ethernat outlets (like behind the TV in the living room, where the home theater I would most likely hook the player up to is located.

Do I need to pay for an additional IP address? If I connected the empeg to the outlet with a cable, would it show up on the network (like in network neighborhood)?

I'm not quite sure how networks work quite yet, because I'm going to have to set all this up this summer when the house is finished. If I have emplode set up on my computer, and the player connected via the outlet in another room, will this work?

Thanks in advance.
