I think I understand the intended behavior. I think it is  
insufficient for anything non-trivial, though I cannot provide hard  
facts because no one could try that part out yet because it has not  
been fully implemented. I know a somewhat similar system which allows  
to do more and more efficiently, so that's what I'm basing my  
suspicions on.

What if these should be available separately even if taken in one  
session? Why is this so different from several etoys projects created  
in one session which should be resumable separately?

The Sugar, Journal, Datastore and Rainbow designs all influence how  
activities function, how they interact, how they are implemented, how  
they store and retrieve data etc. And that is just the core, it even  
leaves out the really hard parts like how collaboration across  
machines works.

Besides, my rant wasn't aimed directly at you or the other coders  
working their, err, working really hard on getting something  
shippable. It's just that the only kind of response we usually get is  
"well, it's not implemented yet, do this or that for now" without  
anybody thinking (or maybe caring to tell others) about the actual plan.
