I was intrigued to see, under the threat from competition commissions around the World, that Microsoft are opening up parts of their code-base and engineering to competitors to make the whole operating system and main applications (Office is mentioned), work better with 3rd party products. I for one hope people like Adobe gets involved with this as a good proportion of the posts in the public GrashesGPFs group on MSFT's servers, relates to faulting add-ins opening with Excel. Hopefully good news...
