Let me try to address some of the comments:

1) any application in QtDBus can emit any signal. All it needs to do is call
QDBusMessage::createSignal and QDBusConnection::send. The library will not
block any sends.

2) any application can receive any signal, from any interface, provided that
the bus allows it (non-eavesdropping). The introspection is not required if
using QDBusConnection::connect.

3) the <interface> entry for org.freedesktop.DBus.Properties in the
introspection is added by QtDBus automatically and it will not include the
PropertiesChanged signal. As long as the receiver side does not require the
introspection, it should work.

4) QtDBus has so far not chosen to implement the signal due to the lack of a
way to be told when a receiver is listening for the signal. I refuse to
implement something that will broadcast useless data on the bus into /dev/null.
