Python COM: Automatic wrap/unwrap?

[Greg Ewing]

I'm creating a COM server in Python that will have one
main class, with methods that create and return instances
of other classes.

I've found that I need to use win32com.server.util.wrap
and unwrap on these objects when they pass over a COM
connection. This doesn't seem very convenient, especially
for methods that can be called either via COM or internally
from other Python code.

It seems that the basic Python types are wrapped and
unwrapped automatically when needed. Is there some way of
extending this mechanism? Is there a class I can inherit
from, or a magic attribute I can set, or some registration
process I can use, to get instances of my class automatically
wrapped and unwrapped?
