Lucy, he needn't mean that at all.
The fundamental rewrite on Drupal looks for a file or directory and if it finds it, it doesn't do the rewrite (ditto for WP).
This means that you don't need any special rewrite to keep Drupal from loading when you really want your static page. Even if you have drupal page with the same URL, it will never load because Drupal will never start up to check the database to look for that URL.
The only place you have an issue is the home page. If your order is php then htm and html, like so:
DirectoryIndex index.php index.htm index.html
Then the first file it will hit in root with the naked domain (i.e. no file spec) will be index.php which necessarily must be Drupal. So you have no means of serving up index.htm as your home page on the plain domain.
If you have the order Broadway is using, you can actually have a static index.htm supersede the index.php file, and you only hit Drupal after a specific rewrite to index.php
That of course only applies to the root directory. Elsewhere there's nothing to worry about.
I've done this with older versions of Drupal where caching wasn't any good and the home page was very server intensive (often the case because it can pull so many pieces from the DB). I'd capture the Drupal output with output buffering, create a static HTML page and serve that up with my home page, regenerating it periodically with... actually I don't remember (a cron job I suppose).
