Have you considered ZMQ? It's quite standard, well supported across languages and platforms, and has great bindings in many languages, including Haskell, and also has a great online "book". I have used it successfully with IHaskell. It does have C library requirements, though.

Hello,
what would you recommend as a message passing library?
Essentially, I would to replace this library http://hackage.haskell.org/package/eprocess
by something more mainstream.
It is used in Hint-server: http://hackage.haskell.org/package/hint-server

Thanks!
