I am so excited to use this, Alex! A hello world uberjar with Skummet is 1 MB slimmer and launches twice as fast on my netbook, though I won't call it a scientific test. And of course you know I'm excited about the prospects for CoA -- have you been testing it with ART yet, or just Dalvik? Great work.
