"serafena" is an acronym of "service request architecture for easy network administration", and combines features of remote execution frameworks, port multiplexers, parallel host administration tools, and adds some service broker facilities.
the current setup allows any user on any participating box to obtain root on any of those boxes with a single command, or access any file on any box, regardless of ownership or permissions.
This makes serafena now unfit for other uses than development on boxes in a trusted environment.
