[Plugin: Cookies for Comments] htaccess Trick on WPMU

According to a comment in this thread, the CFC .htaccess trick won’t work in WPMU.

Is it possible (or does it make sense) to get around this problem by adding the ability to type in the cookie code (*put_cookie_value_here.*) from within the CFC configuration page (or better yet add it to the code itself, so it picks it up as the default like one can do for the Akismet plugin)?
