It depends what everyone means by "COM equivalent". If you mean it as
some kind of distributed object technology, then there are a lot of
CORBA-related solutions out there: ORBit (PyORBit vs. ORBit-python),
Fnorb, omniORB (omniORBpy), and so on. In addition, you have a
selection of unstandardised technologies to choose from, too.

As well as UNO (PyUNO), but that is arguably in the realm of the other
principal interpretation of "COM equivalent": the application
automation technology. On that front, there's ORBit and Bonobo for
GNOME-based applications (I believe) and DCOP for KDE-based
applications. Eventually, there'll be standardisation of such
technologies, and I imagine that D-BUS fits in somewhere here.

Yes. Years ago I had a lot of fun with ILU, but I imagine that any of
the more mature/supported Python-compatible ORBs would be suitable.
Certainly, omniORB (http://omniorb.sourceforge.net/) would be my first
consideration.

Meanwhile, beware of suggestions that you use SOAP or XML-RPC! If
remote method calling is what interests you, such technologies are not
*directly* applicable (unless, in the case of SOAP, XML documents are
the primary representation of data in your system).
