Real-time collaboration

TitanPad and Ether Pad are two very similar tools which allows a group of students to type into the same space at the same time allowing for real time collaboration or co-operation.
Twiddla is a synchronous whiteboard tool like you would find in a lot of web conferencing tools.

Let's try this adding to this titanpad as a group.  Please write the names of types of tools which you think have potential for use in your context?
