Webspiration is Inspiration online. It is in beta now and free, so use it while you can. You do not need Inspiration on your computer, and you can work on documents online. When you are on a computer that does have Inspiration loaded on it then you can download the document to your computer.
I can see students using this by uploading a teacher/or their own prepared template to their own Webspiration account; working on it online at home; coming back to school and downloading it for marking or sharing. If students have their own accounts they can also collaborate on documents together online.
Documents can be embedded for viewing in blogs and wikis, click on the document window to see a blown up version.
R rating: None that I could find
