Open Source IP KVM setup with a Raspberry Pi and an Arduino; now with added USB VGA capture

Here is the next video with the USB capture working and I have also added some extra features, to try to emulate the more expensive setups. I have used the IPMI system that comes with Supermicro server boards and I remembered that they have a way of powering the machine on and back off. I noticed that not too many people had tried to use servos to press the buttons on a PC, so I decided to give it a try and you can see the results in this video. The USB capture quality is not that good, but at least it works and is reliable. I have had the system running for a few days and it has not crashed, or the usb devices have not disconnected, so I am happy becuse the reliability of the system is my only real concern and it seems to be doing well so far. There is one last feature that I am trying to add from the IPMI server systems and you you can see it in the next video which I have already recorded, but still have to put the footage together.
I will try to upload an image of what I am running on the Raspberry Pi, because I had to compile the Turbo VNC, which is a multi threaded VNC server and it comes in handy for taking advantage of the Pi's multiple cores.

couple of questions about your implementation:
1. Why use an arduino for the HID, when you can set the Raspberry Pi to emulate an HID keyboard? There are several projects out there that can help set this up
2. Why go the servo-presses-button route instead of using a relay or transistor or other to short the wires for the power and reset buttons? Is it just so that this doesn't have to be an invasive project to add to the host you want to control?
3. What VGA to composite converter are you using, and what USB composite capture device? There are many out there, including generics of questionable quality, so I'm curious what you used.
