I noticed a comment thread on Groklaw about Moonlight, with a link to the license terms on Microsoft's website. They call it Covenant to Downstream Recipients of Moonlight - Microsoft & Novell Interoperability Collaboration . A comment by Microsoft's Brian Goldfarb on Dana Blankenhorn's article about Novell being a lead pony for Silverlight started the discussion originally. Goldfarb represented that anyone can use Moonlight: "Moonlight is usable for anyone on any distribution of Linux (redhat, ubuntu, etc.) -- it is not limited just to Novell as Mono is." And he linked to the covenant, saying it "applies to all downstream recepients of the software." Is that true?
