Microsoft has released XSource for Visual FoxPro 9.0 SP1. This download comes with its own license agreement, dubbed the Microsoft Permissive License (Ms-PL), which overrides the VFP 9.0 SP1 license agreement with respect to the XBase source files contained in the XSource download. In his January Letter, Microsoft Visual Studio Data Products Manager Ken Levy states "Our goal is to encourage VFP developers to enhance and redistribute any of the VFP 9.0 Xbase components in XSource to share with the VFP community including via the SednaX community project."
A quick glance at the license shows that Microsoft is granting us the rights to reproduce, prepare derivative works, and distribute this stuff royalty-free worldwide (this is my interpretation - I am not a lawyer, so read the complete license and get your own legal advice). There's no question this is going to stimulate a lot of good and creative things to come. Right now I'm off to read the license more thoroughly and to explore what's in the download.
