One variation we request is to augment the types of work being covered. The current PPL is so specific about applying to literary and artistic works and phonograms that it seems to exclude software. Or open hardware designs, for that matter. And in each of those other domains, particular aspects of derivative works arise that are different from those described in some detail by the PPL for the works it covers.

If we can help, please describe how in this comment thread. And maybe other software developers who are interested could register their interest in these comments, or in the described method for collaboration.
