Simon Tatham has a sudoku program which generates Sudoku's of any size in
varying difficulties:
http://www.chiark.greenend.org.uk/~sgtatham/puzzles/
It's down at the bottom and is called Solo.
I can't speak to the actual quality/difficulty of the puzzles, but every
feature you asked for is there plus unlimited puzzles.

Folks:
For research on the behavior of parallel Haskell, does anyone know of a source for graded (easy through evil) 16x16 Sudoku puzzles? Our hardware runs too fast for us to get meaningful timings on 9x9's. I suppose we could insert time wasters, but I think that would also distort the results . . . .
Thanks in advance,
