Dave you could press the update button and get the packages.
It was taking time and was slow but for normal changes it worked.
Now we did a lot of changes that did not work well with MC. So the  
stream could not really be used. But our goal and process was really
to stick as close as possible from an update stream.
May be giving a try to MCConfiguration now would improve the speed.

Sure. This is not that we did not want.

This is also why we provided image when we saw that is was too slow.
Do you imagine the amount of time it took us, because before submitting
an update item, we load it and verify and produce the script and

I'm sorry but MC stores this information so we have it. Now it is not  
in a CS

Good. this is important to give feedback and we knew that this was not
what we wanted. But this proved that MC can be used (avi was even  
surprised that
we made it) Because squeak is more complex/badly layered and biugger  
than any single project.

So now we should learn and continue and really improve.
This is why I would like to find some times to help MC2
