Hmm...we could make the stdin of the executed script hook up to the
installer, so as they read from there they can get installation progress
info.

Something like:

#!/usr/bin/perl -w

while (<STDIN>) {
    # the main setup process just keeps writing percentage strings to
    # this pipe, and EOF when it's done.

    print "installation is $_% complete";

    if ($_ <= 10) {
         render_feature_screen_1();
    } else if ($_ <= 50)
         render_feature_screen_2();
    } else if ($_ <= 80) {
         render_coming_soon_screen();
    } else {
         render_thanks_for_purchasing_screen();
    }
}

exit 0;


...obviously, it doesn't have to be perl, it can be anything that can be
executed and read from stdin, but that might be interesting.
