One point that has been glossed over is chain tension.
The trackends are great for adjusting your overall chain tension precisely, and you won't need a separate tensioner.
However the perfect chain tension may not be at the forward end of the trackend slots. In fact it shouldn't be because then you can't drop the chain off to remove the wheel.
There's a solution though, called a Surly Tuggnut
This item will hold the axle back at the right distance to give enough space to let the axle move forward to create slack to pop the chain off either chainring or cog, and then get the rear wheel out.
Other points - you will still need the anti-rotation washers, but I can't be sure how they would stack up, ie in what order.
Secondly, if you have a full rear mudguard/fender, then you will need to loosen off the rear stay to get enough space for dropping the wheel out for punctures etc. Consider how that might be done easier, perhaps with a clip-on style?
