Concerning the cabal dependencies problem. I didn't tested it yet, but I believe a sane solution should be to use stackage[1].

I know fpcomplete use stackage for their School of Haskell[2]. This way, there is never any package dependency problem. Which gives them the incredible ability to execute yesod application directly on their server from the code of an user changing the code in the browser. If you haven't did it yet, you should really try it.

Also, concerning the deployment, having a single statically linked binary is very similar to having a single jar file. And this is very easy to deploy using heroku for example.

You can ask me more detail if you want to know how I deploy my application but this is mostly very well documented in the wiki.
