Offray,
Nice to see the advances of the Squeak people on the olpc/2b1 platform. I have downloaded the OLPCPlugin.image.zip http://tinlizzie.org/olpc/OLPCPlugin.image.zip and it works like a charm including Spanish support. Will be really a charm to work on olpc in the creation of multimedia educative Spanish content using Squeak.
Thank you for testing. While we haven't done so much testing on the translation part of system, we sort of tried not to introduce new (natural language) phrases. So, the user expecience of non-English native speakers should be relatively comparable with the Squeakland eToys.
