@MartinK: I'll probably have to port server's GUI to QtQuick then. This should be relatively simple and would allow using the server simply in Linux. Right now, console interface is rather un-intuitive and hard to use.
Corresponding issue is opened, let's see when I can make it.
As soon as proper GUI is ready for Linux, would be great to package it for Fedora. Although, it will require packaging of Valhalla, probably.
