If these are Bezier patches, then the outer control points (the four
corners) will be shared with the neighbours; two corners per 
neighbour. This seems to me to be equivalent to finding adjacent 
triangles using shared edges, which certainly isn't complicated math 
(although the simplest implementation takes O(n^2) time).
