I currently have two PS3 systems. One of them is located in a 3 car garage that I remodeled into a dedicated theater room. The other is in my living room. Why have two PS3's? Well, I wanted to have a Blu Ray player in each room, and I also wanted to be able to enjoy PS3 games in each room. I wanted to do this without having to constantly move my PS3 around.
I'm also interested in having the ability to use this PS3 with a HDTV in my bedroom, and also with a small LCD in my kids room. I started thinking that maybe I could just have 1 PS3 system, and have a switchbox, and run wires in the crawl space above the ceiling to the 3 other rooms. Of course, there are alot of issues to think about when doing something like this. The biggest issue is how far will the bluetooth controller signal travel? If I located the primary PS3 in my living room, then I'm pretty sure the bluetooth controller signal would work in the master bedroom, and the kids bedroom, because both of those bedrooms aren't too far away. Unfortunately, I don't think the bluetooth signal will work all the way to the theater room (garage). So, I'm guessing I'll need to run a USB cable, but if it's longer than a certain distance, you have to have some type of usb repeater or something like that. I'm wondering if that will cause a lag in the button presses for various action games.
As for video/audio, I basically just run long HDMI cables to each room, and have them connected to a switchbox where the PS3 is located, and then just switch it to whichever room I'm using at that time. This creates some issues as well, because I don't have a HDMI capable receiver in the living room, or in the master bedroom. The kids room, I could just run the HDMI right to the TV, and use the crappy TV speakers for the sound.
Anyways, I'm basically just thinking aloud here, and wondering if anybody else has already tried doing something like this, and what kind of success they had, or what kind of issues they ran into that they weren't expecting.
