Woking in a Collaborative asinchronous way on Etoys

Hi all,

I'm trying to work with my students on a Etoy project, a Lemmings/Pingus 
Clon, where every student select a feature of the game: Making the 
creatures fall, blown up, drag (horizontal and vertical). Now we want to 
integrate all the work. There is a possibility to make this on Squeak 
(using a superwiki, Monticello, anything)... or the only way to 
integrate the work on Etoys is redoing it all on a project?

Cheers,

Offray
