[Evgenij Spitsyn] spotted a KVM build on these very pages some time ago. It captures the video output, while presenting itself as a standard keyboard and mouse device. The video output of the machine is streamed in MJPEG or H.264 format. The device is capable of serving up storage from a micro SD card or the onboard flash, as well as handling things like power/reset control and wake-on-LAN. Meanwhile, if you found this build interesting, you might like to scope out the one that inspired it.
