NAS is a pump and dump coin. It has nothing new to offer. Even calling it a clone or fork would be a compliment they don't deserve, because it is not, it is a quick and dirty copy and paste job. And believe me, it is dirty - I actually took the time to look at the source, out of curiosity what they did with my code.
NAS have taken a test version of the new Nxt UI, developed by Wesley, which was not yet ready for production use - but they don't care, it is a get rich quick scheme, nevermind that it is other people's money this software is supposed to handle. They have also based their release on a Nxt version with a known critical vulnerability, which was fixed in Nxt long ago.
The NAS marketing guys are aggressively trying to bribe various people in the Nxt community with "giveaways". This is a thinly veiled attempt to make their "software" appear sanctioned by the Nxt community. They have also approached me with a similar offer of a generous donation, but I am ignoring it, because I do not want my name to be associated with this blatant scam.
Never confuse copy and paste jobs like NAS with legitimate Nxt alternatives. NEM and NXTL are trying to innovate and improve on the ideas brought by Nxt, they are apparently re-writing and re-designing everything from the ground up, and will be a healthy competition to Nxt. So they have my respect. But NAS... I hope I made myself clear.
