Hi Tom,

That is just amazing! For those who are not interested in speed that
is a good opportunity to start using dbus + python on Windows while
dbus-python is being ported.

The only thing i miss in txDBus comparing to dbus-python is the way to
export services/objects.
In dbus-python there are dbus.service.BusName (Service) and
dbus.service.Object with dbus_method and dbus_signal decorators.

class MyObject(dbus.service.Object):
  @dbus.service.method(interface, in_args, out_args, ...)
  def sum(self, a, b):
    return self.sumCalculated(a + b) # emits signal

   @dbus.service.signal(interface, signature)
   def sumCalculated(self, sum):
     return sum

Anyway good start. Keep improving it!
