Is this cross-language in the sense jython can use beans? Or in the sense
like CORBA? I assumed the former, which isn't cross-language in my
perception (at least not in the general sense, as CORBA is)

Sure, as I can do it in jython. But the key point is: can your ordinary
python-object be published as a component? At least for jython I can
say "no", you will have to subclass an already existing
java-object/interface. And I have difficulties imagining that it is any
different in .NET - because I've read statements that claimed that the
structure of the VM/runtime is orientied towards single-inheritance
statically typed languages as C#/java.
