RealtimeBoard

This is an amazing collaborative whiteboard where multiple users

 can edit a multimedia board in real time. The site allows you to 

signup and sign in using a Google account and you can access 

and add your files and media on your Google Docs/Drive area

making this a fabulous companion to schools using Google Apps 

for education. You can write by typing or you can write in 'freehand'

 so you can use your interactive whiteboard to write and archive

 the lesson to use or refer to later.
