Thanks! I'm glad to know there's an easy way to get this done in the short
term without having to install PyObjC, even though long term I will
probably want to have PyObjC deployed as part of our standard Mac
configuration.

We have already crossed that bridge by hiring a developer (Walker Hale) to
build a Python module to do that. He came up with a way to do it using
Python's built-in support for Carbon on OS X. I'm hoping my employer will
allow me to post more of the project code publicly, because we can benefit
from "open source" scrutiny, and because some of it may prove useful to
others.
