John,
Mind I suspect the Squeakland.app in the OLPC-Etoys070726.zip should not contain the Squeakland.image since I think it's replaced by the etoys.image? Er this makes the zip file 2x as large since there are two images in the zip file.
Oops. There shouldn't be another image (other than etoys.image) in the zip file. For the next round, I'll make up with a zip file that follows Sophie structure, I guess.
