I vaguely remember this being brought up at the time of the first PIPE done by Roger Stoll. I believe a couple of fairly large shareholders approached him about this. I do not remember the details, but I believe there was some SEC-related concern regarding vetting investors' net worth, rules regarding the number of people involved, and the interaction therein--i.e. you had to have a relatively small # of people putting in what for individuals like ourselves would be a lot of money. Dew or Gfp may recall the details better than I do--I just recall concluding that SEC regulations made it a lot more difficult than I would have thought.
