I recall hearing about this a while back, and how the team at Meta had implemented hotswapping to deploy new rules, without redeploying the entire executable, even though the rules were expressed in a Haskell DSL. Unfortunately, I have never seen hotswapping of Haskell code anywhere else. All I can find is this library [0] by Simon Marlow. Together with Cloud Haskell [1], hotwapping would allow to create pretty flexible distributed systems à la Erlang/OTP.
