Hi Lane, I've recently implemented the option for future/early distortion cost (-edc) that you were asking about:
As proposed in the paper, this doesn't really work as a future cost that's kept separate from the distortion model score, but rather as an alternative to it: "Our first improvement [...] is to incorporate an estimate of the distortion penalty yet to be incurred into the estimated score for the portion of the source sentence remaining to be translated." (Moore & Quirk 2007) I've tried the option on some Arabic-English benchmarks and got the expected improvement by using a DL slightly higher than my baseline.
