We wanted local server only (not in process) for our application as
well.  Here is what we did.  In our com server class that we use when
calling register(), make sure this attribute it set:

class MyCOMServer:
    # ...
    _reg_clsctx_ = pythoncom.CLSCTX_LOCAL_SERVER
    # ...

We also package our application (mojonation) up using py2exe, and have
the python registration code set "pythoncom.frozen = 1" before it
calls register() on installation so that the path to the actual .exe
is registered with the OS so it can be installed and run on systems
without python installed.

[I never found any docs describing those tricks in an obvious manner;
playing around and reading the win32com source code led to finding
that solution]
