I'm on my HOA and I imagine the hardest part of making this work would actually be sales. The sales cycle for an HOA would be multiple months between meetings and actually making a decision. Then there's the issue of rotating responsibility, retraining, no guarantees of technical skills among board volunteers.

I'd tend to agree with the other comments that the hired out management companies would be a much better sales target since they have a real profit motive to efficiency gains. At best a neighborhood HOA is looking at periodically saving some time and being a bit better organized.
