Microsoft common engineering criteria

I followed a presentation about Biztalk 2004/2006 when I first heard about the Microsoft Common Engineering Criteria, these are a common set of guidelines and requirements that each infrastructure server must meet. They also give a pretty good idea about what to expect from future releases of MSCMS, SharePoint and Biztalk, I especially like the following:

64-bit support

.NET Connected

MOM management pack support at launch

Virtual Server support

There are of course a lot more, read more about it.
