I do think that will be the way to really start the "human exploitation" of space.
The question is: How do we get there from here.
NASA needs to start developing manned space launch alternatives to and replacements for the shuttle. And they need to do it in a way that encourages Private sector envolvement.
Heck, they could keep the shuttle flying for missions where humans and cargo must be launched simultaneously and develop new alternatives for human-onlt or cargo-only missions.
In short, they need to change the "all in one basket mentality that has hamstrung them ever since the shuttle was little more than a glint in some Administrator's eye.
