You can share the URL for the project, or even embed the project into a blog or wiki, and the viewer should not be able to make changes. The projects are all protected and only the owner of the project may make changes by logging in to their account and editing the project. This is the same reason teachers may not change a student's project.
If you click on this link, http://wixie.com/s433181, you will see how a project is displayed for viewers through the Wixie Presentation Dashboard. Since you are not logged in as the student, you will not be able to edit the project, or even view the grade for the project. All you should be able to do is view the project.
Please let us know if you have any further questions.
