[Haskell-cafe] Deploying a Binary Haskell Package

This question isn't directly related to Haskell, but I figure some one might know here. I want to deploy an application. I could either: 1) Tell people how to download GHC, have them check out the repository, have them install all the needed hackage packages, ... or 2) Give them a setup.msi/exe I'm curious if any one has done this with a Haskell package. It seems that it's something that might make sense being integrated into Cabal (runhaskell Setup msi). Either way, has some one deployed a Haskell binary as a MSI package? /jve
