I've never done it but what about those Di2 external cable guides/strips?
That's a very tidy solution.
They're in my mind because the Tripster I've got coming doesn't have a hollow chainstay all the way along its length so the Di2 cable would have to be run externally and I remember these from the original Di2 setup days.
