Aqua, my very limited understanding of this issue leads me to believe there would be a way for any investor with verifiable assets to participate, if invited. I believe the regulation requires an investor to be "qualified", but I am guessing there are few real qualifications other than (1) being of sound mind and (2)having the money, and they would probably waive the "sound mind" qualification. I'm joking of course, but I think having the money and the invitation are the only real requirements.
I am only expressing my personal opinions or repeating public information from SEC filings or media outlets-which may or may not be correct. Do your own investigating before investing!
