As someone who has ported Network, Comanche, Seaside, Scriptaculous
and ShoreComponents into my GUI-less image, I can say it was not
complicated. Scriptaculous and ShoreComponents was out-of-the-box. As
far as I remember, Comanche was also not problematic - only very few

During porting of Seaside, the most problematic was absence of image
read-writers and some small issues like direct usage of Morphic
instead of UIManager (because of backward compatibility).

I think that we should split Seaside package into two or three
packages and create something like Seaside-Loader (see
ShoreComponents) to be able to strictly detach Squeak-dependent stuff.
That will make porting to VW (and other platforms) more easy and it
will also help us to load this package into the kernel image.

I may try to load the latest versions of this packages again and
report problematic code. Maybe Michel Bany should do the same.

The next step is to port MC for the kernel image but it needs to
enforce some refactorings in the Squeak (split ChangeSorter) and so
