Along the same lines, once or twice I've needed to create a "desktop"
version of a web app, which is what I wrote wai-handler-webkit[1] for.
It only really builds properly on Linux for now, but if the need
arises I don't see any reason it wouldn't work for Mac/Windows as

Web applications, especially with an HTML 5 front-end, have become increasingly more powerful. If we can also find a good, standardized way to generate JS from our Haskell code, we're pretty much all set.
