That's cool ND, my hats off to Blue Sky then, because I like NURBs, and I have used much better NURBs modeling apps then Maya, and if Blue Sky uses NURBs (and I mean beyond just starting forms, which includes using the round, fillet, square, stitching and boolean tools) and Maya, I give them a lot of credit.
