Potential projects

A common lament in #haskell is that someone would like to write some Haskell code, but can't think of any code to write or problems to solve. So, here's a list of potential Haskell work -- it could be GHC modifications, creating Haskell bindings for existing libraries, or just writing new applications in Haskell. Feel free to edit liberally!
