I just was going through the iRule software. It seems like they borrow A LOT from harmony. The way "activities" are done and even the way one choose what gear and product they have.

I do think it is cool that it supports IP/232, which I doubt harmony will ever do, but that is because IRule is harnessing the power of the GC units.

My first impression is Harmony 2.0. It's really hard to even compare iRule to CCP. One is clearly a custom professional product and the other feels very DIY. That's not to cast judgement in either direction on the products.
