I think the way to do Erlang in Haskell is to build a middleware layer 
on top of the language, not try to make the language into something it 
is not.  In this kind of environment you need to be able to upgrade 
components while the system is running.  The careful Haskell habit of 
separating stateful operations from pure functions is useful here.  I 
gather that the HAppS project is working along similar lines, and for 
similar reasons.  Take a look at it.
