ndesk-dbus is a C# implementation of D-Bus. It's often referred to as
dbus-sharp, or "managed D-Bus" to avoid confusion with existing bindings 
(which wrap libdbus).

D-Bus is an inter-process communication framework that lets applications 
interface with the system event bus as well as allowing them to talk to one 
another in a peer-to-peer configuration.

This requires Mono.
