I guess the thing that worries me about a game like this is that it divides the players into very seperate populations. One of the biggest issues faced by text games today is the ability to grow, and it takes a crowd to bring in new blood. In my opinion, the design described on the linked page would isolate two-thirds of the players from each other and essentially create three separate games. I don't believe it's ever a good idea to implement built-in barriers to interactivity and communication. The pool of people interested in text gaming just isn't big enough, no matter how good a game design is.
