<snip> Hi, As per the language included in the section of the FAQ that you reference above, if you want to go down that path, you would have to engage in formally communicating with the R Foundation, as the copyright holders of R, to solicit their formal position, which would be final. Note that depending upon the specifics, there may be other parties that would also have to render a decision, since other individuals also hold copyrights to included code in the standard R distribution and may or may not have given approval to the R Foundation to act on their behalf: https://svn.r-project.org/R/trunk/doc/COPYRIGHTS If you wanted to pursue that avenue, you should communicate with the current R Foundation Co-Presidents: Simon Urbanek (simon.urba...@r-project.org) Martyn Plummer (plumm...@iarc.fr) were they can elect to engage the Board of the R Foundation in further discussion. To the broader issue of the "stance" of the community at large vis-a-vis closed source software, you will find, as in any community, a spectrum of positions. There are, as you may be aware, commercial versions of R, that have been built upon the standard open source R distribution, which offer sufficient additional value that their customers are willing to pay for them. In some cases, these may include closed source components. A parallel of sorts would be a community based, open source version of a Linux server distribution (e.g. CentOS) versus a commercial offering (e.g. RHEL), where the latter has paid support options and other value added components and services that are revenue generating. In these commercial cases, as I referenced in my prior reply, legal counsel with expertise in open source licensing and intellectual property rights, will have rendered formal legal opinions to provide guidance and comfort that these for-profit businesses remain in conformance with license requirements to stay clear of any liabilities. No ethical business, in their right mind, would move forward without that. However, at the end of the day, the only position that is relevant to your issue is the formal position of the R Foundation itself, since it holds the copyright to R as officially distributed and would, if needed, take action in the case of license non-conformance. Others in the community, myself included, can offer opinions, but they hold no relevance to your situation, since they are not legally binding. In other words, we are not in a position to say that you can or cannot proceed with your plan. You can gain some insights, as others have referenced, by using examples of what appear to be acceptable implementations. But each situation can have sufficient differences as to perhaps not be exactly applicable to yours. Thus, part of the potential challenge for you would be to provide sufficient detail on your exact implementation plans to allow an opinion to be rendered that narrowly covers those details, as opposed to a more generic model.
