Cabals' Paths_pkg and GHCi

a general question about cabal and ghci:

if I have successfully loaded my project files into ghci, I've presumably
set all the right flags and paths, for ghci. 

if I have successfully created a cabal project, I've presumably
encoded all the right flags and paths, for cabal.

would it be possible to add a "cabal" command to ghci, so that
we could:

    - create a cabal file for the currently loaded project
    - load a project from a cabal file

or does this make no sense? doesn't visual haskell do something 
like that, using cabal behind the scenes?

cheers,
