The program is really nice. Basically you can view and edit a document from many different computers all at the same time. Whatever you write shows up instantly on someone else's screen highlighted in a color that defines that edit as 'you'.
You can save multiple revisions of the document and load any prior save you want. There's even a nice chat function, although generally I have been using skype while discussing everything.
I thought it was pretty neat and thought some people on this site might be interested, for bridge purposes or otherwise.
A downside for bridge is that you can't insert neat ♣♦♥♠ symbols. (Maybe you can pirate this technology and create the world's best system-note maker, Fred?
