I know how to randomly shuffle an array. 

sub fisher_yates_shuffle {
        my $array = shift;
        my $i = @$array;
        while ( --$i )
        {
                my $j = int rand( $i+1 );
                @$array[$i,$j] = @$array[$j,$i];
        }
}

How can I rig the shuffle so that the results are always same on any given host but, random between different hosts?
