	Many people might be interested in the answer, so I'm posting
as well as responding (not to mention that it's rather poor net
etiquette to say "just respond to me, I can't be bothered reading this
newsgroup for the next couple of days").

	Redirecting cin/cout is simple:

        ifstream        infile( "infile" );
        ofstream        outfile( "outfile" );

        cin = ifstream;
        cout = ofstream;

        cin >> something;	// Comes from infile
        cout << something;	// Goes to outfile

        If you want to restore cin and cout after doing the redirection,
you can do the following:

        istream_withassign      save_cin;
        ostream_withassign      save_cout;

        save_cin = cin;
        save_cout = cout;

        // Redirect cin and cout
        // ...

        // Restore cin and cout
        cin = save_cin;
        cout = save_cout;
