So I've bought the nanokvm-usb. Why: I needed it quickly and was available the idea of going through another server for secutiry seemed better: I control the updates and security fixes well tested on the internetthe product itself costed around 50€ and I found a used mini pc with wireless connection for 25€ it was easy to install, works fine and is of good quality
Hugo is exactly the kind I don't want, WYSIWYG is important :D
