Besides those functions I also wanted to be able to easily stop my torrents from uploading and downloading when I was using the media server. I keep all my media server folders on the same RAID drive as where I do all my uploading/downloading so I want all IO to be dedicated to the PS3 when I am streaming or transcoding. I like to FF, REW, and GOTO frequently.
I am going to try to make this easy for those who are not programmers or web gurus but to put in every detail is too involved. You may need extra help to get it all working. For the experts, you will be able to customize this to fit your needs. I am splitting this solution up into 3 posts.
1) Turning on your PC from the XMB
2) Controlling your PC
3) Controlling uTorrent bit torrents
To accomplish these goals I am going to be utilizing the PS3 web browser but do everything with an infra-red (IR) remote. The PS3 remote control is blue-tooth. I have a universal RF master remote that controls several infra-red devices in my living room; one being the PS3. To add the PS3, I bought a PS3 infrared remote and programmed it into my universal. (It comes with a dongle that you leave in one of the USB ports). You don't get every button on the blue-tooth remote but you do get everything on the game controller. The circle, triangle, square, circle, up, down, left, right buttons are required for this solution. You can of course just use your game controller.
Here is a picture of the final product:
