Hi,
I am looking for a way to extend GHCI such that I can do something
like this
$ ghci
GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Prelude> startMyFunction

startMyFunction will do a forkIO and listen on a network port for
interaction with a remote process and will drop back to GHCI prompt
where I can invoke haskell functions that'll control the way the
interaction with the remote process occurs. Can this be done?
I am not sure that I understand you correctly, but ghci simulates the IO
monad, so what about:
Prelude> :l MyModule.hs
*MyModule> conn <- waitForAndAcceptConnection
*MyModule> someData <- getSomeData conn
*MyModule> sendSomeAnswer conn $ processSomeData someData
...
