This is a classic Sudoku involving what I believe is a new kind of deduction. All of the Sudoku grading software I have found gives this puzzle a very high grade and can't solve it using human techniques, but there is a very simple piece of logic that solves the puzzle.
I hope you enjoy and I'd love to hear your feedback in the comments!

Now that I solved, I'm glad to see that I solved the way you intended, it took me a while to spot it, but it was very nice :)

And I'd of course be interested to know whether any of you have seen the logic used in this puzzle before!
