Thanks! While I currently don't have time to directly contribute to the Braid chat, I will definitely provide support for Dunaj, if you choose to use it. I suggest to start with Dunaj lite, which plays nicely with existing Clojure, so you can introduce it gradually into your codebase.
As for the support in Clojurescript, I haven't yet figured out the bootstrapping process completely, and I'm waiting a bit for eval support in Clojurescript to mature a bit, as this feature will help me a lot.
