Want to know more about iCampuses (or Web Campuses)? Here are a few more links:
These are a few sample iCampuses. Note that there are definite "church times" when greeters and even campus pastors are available.
On a more informative note, here's a little about the results they're getting at an Australian Church iCampus (no tech), and some Notes from an Internet Campus Webinar (lots of tech).
Finally, there's even an article on a new tool that lets people chat on an iCampus even though they speak different languages. (Think of it like Trek's Universal Translator.)
