This sounds like something worth trying to me. I'm trying to think of
libraries I would definitely see in such collection of libraries.
bytestring jumps to mind immediately. A fast and stable HTTP package
based on bytestring that supports developing web servers would be very
nice too (I'll work more on this when I have time). The idea is
basically that you implement a function of type:

myApp :: Application


type Environ = Map ByteString ByteString
type Headers = [(ByteString, ByteString)]
type Application = Environ -> IO (Headers, ByteString)

or something along those lines (i.e. a stream of user data is missing
in the above example). The point is that I want to be able to do:

import Network.WAI.Server (simpleServer)

main = simpleServer myApp

and have it just work. Sorry for the ramble. :)
