Göran,

I'm surprised with the lack of response to your post. Maybe people are letting 
it sink in. I think it's a great idea. FMPOV, the tool would be a clean way 
for the developer and user to accept bug fixes into his image. Why not make 
bug fixes easily available to everyone? It's also a nice way to put a method 
around all the fixes just lying there in various forms and places. And, it 
seems a nice way to update released images on ftp.squeak.org with proper 
fixes - at least the fairly new ones. 

The concept and high-level usage is a no-brainer. The tough part is getting it 
done.  Since a lot of the work is creating the tool description, and you have 
a great handle on that already, I wouldn't be surprised if you've already 
started coding.
