San Francisco Distributed Library Project

What happens when people in the Real World try to imitate the Meta Library:

http://www.communitybooks.org/

"Create an account, then list the books and videos that you own.  You will then have access to the multitude of books and videos available in other people's collections.  You can search for specific authors or titles, browse individual collections, find nearby users, or find people who like books in common with yours. You will have access to user-written reviews and have the opportunity to write your own."

I have difficulty seeing this working, neat though it is.
