It states very clearly that one is permitted "to make commercial use of the work." As for derivative work, the elongated criterion is as such: ""Derivative Work" means a work based upon the Work or upon the Work and other pre-existing works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which the Work may be recast, transformed, or adapted, except that a work that constitutes a Collective Work will not be considered a Derivative Work for the purpose of this License. For the avoidance of doubt, where the Work is a musical composition or sound recording, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered a Derivative Work for the purpose of this License."

The license is not exactly clear on what a derivitive work is. And the lawyers have not gotten back to me with answers about this and other questions. As far as public domain goes, I don't think we should do that really. It would be nice to encourage people to give something back, and just having the icons as public domain, means that we can't retain any ownership in the form of copyright, and that we are basically doing work for free, for other people that are going to charge for the work we did. This is not exactly fair, or even economical. The short answer is that we are waiting on feedback from legal to answer several of these questions, and to resolve all of the license issues. -- dobey On Thu, 2006-05-04 at 14:19 +0200, Benjamin Apel wrote: </pre> <blockquote type="cite"> <pre wrap="">Hello alltogether, just one simple question: is it allowed to use these icons in a commercial closed source app`?
