Protocol specs are actually pretty easy. The protocols aren't that complicated, and there's some pretty simple ways to figure them out. It's usually an hour or two per new device, at most. Everything that v1 rust does right now, our C#/JS versions did before, so the technical work there was mostly fitting it from gc'd runtime'd languages into Rust. I'm much better at Rust now though! The majority of the work technically AND design-wise (for me at least) is the haptics abstraction. Our protocol is built on a system of "verbs" at the moment, i.e. "vibrate", "rotate", "stroke" (though we call it linear because it only goes one direction at a time), etc... I'm writing a larger blog post on this, but to summarize, it's REALLY hard to build a language around this that's general. For instance, the Lovense Max (a onahole style toy) has an air bladder that inflates/deflates. It's about the only thing that has that. So do I just make a new verb called "inflate"? Do I try to match it to other toys with constriction like systems and call it "constrict"? Does it even matter? But, that's an ongoing problem. In terms of "done", I think the next big milestone will be mobile app support. We work on mobile web browsers in a couple of different ways, but Buttplug still needs app support, both native and for things like cordova/react native/etc... The biggest issue there at the moment lies in our bluetooth library (btleplug, https://github.com/deviceplug/btleplug https://github.com/deviceplug/btleplug), because getting the FFI via JNI to android is going to suck (even though I can crib off Servo's WebBluetooth impl, which worked on Android).
