Ok so it's only for three people, but Bigelow Aerospace is committed to having their Sundancer module launched before 2010.

This is private enterprise at its best.  Let's review.

Paul Allen is involved with Space Ship One / Scaled composites.
Richard Branson also.
...and Northrop Grumman buys the company.

Elon Musk is working hard with SpaceX on the Falcon project.  Successfully launching a Falcon earlier this year.  Impressive in most accounts.  He has revenue coming in from scheduled launches of satellites (whether that covers his costs is unlikely).

And now we have the ambitious plan of Bigelow Aerospace.  This is an unprecedented influx of private industry into the space exploration realm.

The design of the Bigelow modules are very innovative...they inflate once in space.  As long as the interior is sufficiently safe, this is a very cool evolution.  Space stations cubic interior space would no longer be limited by the carrying volume of the launch spacecraft. 

If it is scalable, it would make vastly bigger constructs possible in space.
