I understand Microsoft’s interest is clearly connected with selling proprietary software, no question about it. Despite this, ISVs could plan to develop free software applications on top of their proprietary infrastructures, and I wouldn’t mind, just as I don’t when proprietary vendors let their software run on top of (GNU/)Linux.

Does it scare you? Despite a full free software IT world might be better, I see the hybrid taking over and over, and that would be just another flavour..

About Moonlight I share your and Matt vision, but that’s is a completely different story.. I really can’t see a reason to not be happy about seeing VARs developing free software applications, there are lots of them and Plexnet and similar initiatives prove it to be meaningful.

Last but not least, the interoperability issue it’s still a huge problem, and I am happy that FSFE is keeping the ball rolling!
