May be also others (including the libreoffice team, e. g. dtardon) are 
interested in those files. Is there another (public) way to share those files 
easily? (May be github or  something like that)

Ok, so it seems to be at least an alternative.

Over all, the SDK seems to be not as platfrom independent as the LibreOffice 
project itself.
