It sounds like you'd easily be able to extend your work to the datify/nav protocols so your work wouldn't really be a waste. His viewer seems more a proof-of-concept.
Doesn't feel like a waste ;) The time spent investigating different GUIs in Clojure or integrating languages with better GUIs with Clojure feels does like a waste. I eventually settled on plain ol Swing but JavaFX looks quite nice.
clojure.spec was a nice step up to natively dealing with data 'shapes', I'm hoping the datify/nav protocols will be a step up to what I'm doing as well. It's basically a generalised browser over data with different print representations, collection handling, publishing, muxing, etc. The REBL will hopefully raise consciousness of just how abysmal the representation and navigation of the web is today.
