SmartNotebook Express

I was looking around this morning and stumble across SmartNotebook Express. It is a SmartNotebook in a browser. If you already have your notebook file (.xbk), you can open the file in Express. It has the basic commands of the SmartNotebook (draw add text, and add slide) has. The is the beta version, so it may change. It looks to be a good tool for distance education tool.
