I'd suggest adding a page to the APM installation process which offers a form with default values taken from the info file for the to be installed packages. This should only be true for packages that suggest a default value and should be changeable by the user (obviously, why else to have a form :)).
Furthermore, if a package requires the user to have a look at it's parameters for it to be useful, we should link this up from the installation process as well.
Other than that, cool idea Lars !
