It's specifically designed to handle the 3 space+1 time dimension that we have in general relativity. There is a specific mathematical trick (Ashtekar's new variables) that makes use of a group (SU2) that is tailored to this number of dimensions. There may be generalizations to other dimensions but I don't know of them.

One of my main points in my initial post was that I think there needs to be at least a fourth space-like dimension to "hyperspace" if there is to be any chance of success.
