If you can run AOLserver alone, this is best, but from the 3850 Apache RPM downloads (almost half of OpenACS downloads), I'd say that the ability to run on other servers will help us grow, right? And let's face it, while many of us need AOLserver scalability for when we hit it big, many smaller client sites do not aim at a level of which performance will be an issue. A whole lot of these sites run on Apache.
