All the games are implemented in Squeak/Smalltalk. We neither teach Etoys 
nor apply it for our student projects. The course is about writing "good" 
software. The students should realize small games within 3 months and 
present their design decisions, architecture etc. This is the practical part for 
teaching idioms, design patterns, and object-orientation. As Etoys is built for 
children we cannot apply it for these purposes.

I will have a look at it. We have another workshop course for pupils where we 
teach Etoys. More documentation would help us and the pupils a lot.

Yes, you can do it. But remember that these projects are written in Smalltalk
and mostly independent of Etoys. If you are interested in more details about
these projects please contact me (michael.perscheid at hpi.uni-potsdam.de) 
or the students directly (firstname.lastname at student.hpi.uni-potsdam.de).

Thanks for this information. We will fix it. Nevertheless, both licenses should 
work for OLPC and your project.

You're welcome.
