I did the survey and indicated that I would not open my darkroom since it's in my home. However, I built the current one so that it I would be able to teach individuals or give small workshops, and I have done a workshop. However, I have found that locally (North Texas) there just does not seem to be much market for this. There are more than me around that would gladly help a beginner ("vetted" as it were), but beginners are not beating down our doors.
A few local schools still teach B&W. The University of North Texas has quite a large photography program, for instance. But, I believe the last for hire darkroom closed up a few years ago.
