Looks to me like nothing more than a strategy to take on the ACHA and bring more club teams into the fold for the AAU money machine. If you look at the schools that make up the NEIHC division of the CHF, I doubt that Brown, UNH, Anna Marie, Babson, etc. are going to give up their NCAA D-I or D-III status for an AAU program.
No current NCAA team is going to move to AAU. This is a league for their club teams to play in. If you browse the website, you'll see that the New England teams do pretty well.
