Now, that IPO type model (which will also be Etherium I believe) isn't necessarily a scam just because it breaks accepted "rules".
Selling shares of a new tech to the market at whatever price the market will bear, is not scamming. I don't have any evidence that NXT is scamming anyone. I have also sold shares of my companies to the public.
What I don't believe is that these things will become currency. At least my shares have never succeeded on that

I'm not sure the IPO model is even legal (in the US) unless the developers register with the SEC. How is selling shares in Nxt different than selling shares in Satoshi Dice? We know Mr. Voorhees recently got nailed for this:
https://bitcointalk.org/index.php?topic=637435.0At this point I think it is a semantic argument. These 2.0 currencies can be programmed to essentially do whatever they want.
I don't think they sold it as an IPO, but a few people have commented on it as such. If the intention of the founders can't
be proven in a court of law, then where does it go? And even if it can be proven, I don't think a decentralized network is going
to be taken down anytime soon. I believe it can also just be "forked" as it is open source? This is going to be a huge headache
for the SEC or any government entity that tries to wrangle with it imo.
Fun times are a coming...
