If you just want to see broader testing first, a better solution would be for Hynek to just contribute to the Calendar Server project directly so that there are effectively 2 parties involved rather than 3; for starters, we could have a setup.py in the calendarserver.org repository that just submits twext.enterprise.* to PyPI as an independent source distribution, while remaining part of the same project.  It can *appear* to be a separate project as long as it's developed in the same place. :-)
