main = readFile "/dev/input/mouse" >>= mapM print . streamToEvents

That's no easy.

Now I want to listen to those events remotely using a network conncetion
Data.Network does provide everything I need.

Is this done by substituting the print function with something like
sent event = do writers <- getWritersFromMVar
                mapM (sent event) writers

and using another lightweight thread to add writers/connections to the

Would you implement this in another way?
