To change the skin setting to a per-session one, simply set:

    $SkinCookieExpires = 0;

You could also allow the expiration time as an options, by adding:

    if (isset($_REQUEST['skinexpires']))
        $SkinCookieExpires = 0 + $_REQUEST['skinexpires'];

Then one can do ?setskin=foo&skinexpires=86400 to get the setting
to last for 24 hours.  Or, to be really fancy, perhaps:

    if (isset($_REQUEST['skinexpires'])) {
        list($g0,$g1) = DRange($_REQUEST['skinexpires']);
        $SkinCookieExpires = $g0;
    }

Then one can actually use a real date for expiration, as in:

    ...?setskin=foo&skinexpires=2009-01-01
    ...?setskin=foo&skinexpires=tomorrow
