ThinkFold is a web-based outliner that offers sharing capabilities in real time.

From its website: http://www.thinkfold.com/products/

"Realtime collaboration.

"Interact in a shared outline; adding text, images and files, whilst rearranging your ideas on the fly. You simultaneously sees everyone's activity in the shared outline.

"ThinkFold is the perfect way to brainstorm, plan projects and develop presentations together, even if you're miles apart.

Simple sharing.

"Ideas need action. Use ThinkFold to outline conversations in realtime, and turn your agreements into actions. ThinkFold lets you quickly reorganise notes and ideas into structured plans, assigning individual tasks to people sharing the outline."

I haven't tried this product, but plan to do so soon.
