I just have to say that this story is one of my favorites - actually, all three stories in the series are wonderful. Great rec. Also, I just remembered there's someone else who writes Iphicles/Iolaus...well, Iphicles/Jester!Iolaus. Take at look at Nymphica's stories (http://occlumency.amplexus.org/ffhercules.html), particularly Grown In Darkness, if you haven't read them before.
