Yes, I understand that part. I guess the part that I don't get is this:

"Based on their models the researchers assume that a system that will be more than just an attempt to mimic the behavior of black holes will be created. In its behavior, it will be indistinguishable from real black holes."

If it's indistingishible, then it is in essence a black hole, with all that entails, including the fact that no information can escape. The finding by Hawking and Thorne could be a way to get around this limit. I'm sure the researchers have worked out some solution.
