The image is a great thing but it can also be a pain in the behind when 
you try to find
stray objects and processes out of control etc. There is some real zen 
to image hacking that only
a few über geeks are capable of. Building the right tools and sand 
boxing for mere mortals would
help. I remember from my brief HyperCard period that you ran it on 5 
different levels, from
being able to change the whole stack to being able to just run. The 
Squeakland image has a simple
sand boxing but it is still possible to create etoys that recurse out of 
control. I believe some kind of
level of safety could be introduced without sacrificing the turtles all 
the way down experience.
