Plothopping: How to make it possible?

Hi,

The concept (plothopping) of my blog is about thousands (or more) different writers from across the world who write 1 story together on plothopper.wordpress.com. It will be very interesting to see what kind of story all these different nationalities create together and how the story evolves).
Therefor I wonder whether folllowing idea can be made possible by WordPress:

When a visitor (reader and potential writer) opens the blog on his screen, he must be able to see and thus read on the homepage the already written part of the story (every visitor is alloud to post one sentence a day, so the plot is very unpredictable and can be changed completely by every single writer, so that is what I called plothopping). AND THEN when he has read the story or last few sentences, he must be able to write a sentence himself which will then be IMMEDIATELY be joined to the story, kind of pasted immediately beneath the last written sentence. AND when a sentence is then published, all readers at that time can see the new sentence appear underneath, so they know the story has just been changed and they will have to come up with a fitting following sentence.

Can WordPress make this possible?

Now it works with commenting and replying, but the idea I mentioned above would be a lot more interesting!

Thanks!
