I've gotten quite a few questions about what this partnership means, but I think the best response is to point people to Bill Hilf on Port25.

 

Bill is the GM for platform strategy and the original guy who got the Linux/OSS interoperability lab started at Microsoft and the person who I would expect to be the most informed concerning key aspects of the Novell agreement.
At the end of the day, this type of agreement isn't going to make me a fan of Novell SUSE security any more than the big existing relationship between Windows and Oracle makes me a fan of Oracle's security.  In both cases, they need to acknowledge the need to raise the bar on security quality and implement an SDL-like process.
