We wrote our RF radio mesh coordinator software in Haskell, and it's been a great success. Working with binary data formats (various building control protocols) in Haskell is the kind of thing that spoils you forever. The one issue I've run into is that ghc can't cross compile. If you want to run your code on ARM, you have to compile an ARM version of ghc (QEMU comes in handy here).
