heheheheh. We would LOVE that. In fact, I told martin few months ago to do
If you could give it a try or need help, please let us know.

I guess this should be easy to do. For the moment:

- globals objects are hardcoded in #globalNames
- globals behaviors (classes and traits) are managed (by default) in kind of
"light" serialization. Where we only serialize the global name which means
that the class has to be present in Smalltalk globals in the image that you
want to materialize.

You can change the default behavior and be able to completely serialize a
class/trait. But this is much more complicated and it is still work on
process (ClassBuilder is not your best friend).
