Itay, I took a look at Waterfront and it seems to have a lot of potential. Keep me and the group updated on your future work.
I have also been working on a GUI application in Clojure and I share your perspective on the challenges of designing a functional GUI. I am definitely intrigued by the application context pattern and I am going to take a look at it for incorporation in my design.
