Perusing the archives of the scientific journal Nature I came across an article dealing with ethics boards:
Sieber says review boards need to be more rigorous in their risk assessments and decisions, and says they should call in outside experts where necessary. She adds, however, that a more common problem with institutional review boards is not a willingness to allow dubious studies, but an overly cautious approach that comes from ignorance of the experimental methods involved.
I think the moral of the story is: make sure you make your experiment accessible to others so they'll understand what the heck you want to do, or have done. Giles, J. "Warning flag for ethics boards"Nature 443, 127 (14 September 2006) | doi:10.1038/443127 (link).
