Evan asked about the different "waits" that Netflix uses to describe how long it will take to get a movie. This information is in the help section of the Netflix Web site, which is filled with answers to an amazing number of questions.
Q: What do Short Wait, Long Wait and Very Long Wait mean?
A: From time to time, you may see some movies in your queue with a wait status. A wait status is an indication that more customers want to see this movie than we have copies. We recommend that you keep your movies in the order you would like to view them regardless of the availability status, since we will ship all the copies we have, and some people seeing a wait status will in fact receive the movie.
Short Wait: We don't have quite enough copies of this movie to meet all current demand, so we may not be able to ship it to you right now. We should have enough copies in the near future. The wait for this movie is generally less than 14 days.
Long Wait: There's considerably more demand than available copies for this movie. It's unlikely that we'll be able to send you this movie in the next week or two. The wait for this movie is generally less than 30 days.
Very Long Wait: There is very high demand, limited availability and/or a very long wait for this movie. The wait for this movie is generally less than 4 months, but could be longer, for example if the movie is out of print or we are otherwise unable to buy more copies.

Blockbuster has a similar help page to describe the different availability terms:
