IO in the middle

[Donn Cave]

I think you're talking about RPC, "Remote Procedure Call".  A search
for that term turns up http://www.haskell.org/haskellwiki/HaXR

For things like this, it would make sense to subscribe to "haskell-cafe",
and post questions there - it's a much more active list that's devoted
to ideas about Haskell in general, as opposed to specific quirks of the
GHC implementation.
