This is a hint of something more and not a stupid remark as some have said. Although it may not be such a big deal.
"Wave's EMBASSY Trust Suite, developed to the TCG specification and integrated into the Microsoft Office(R) environment..."
The way I interpret that staement is that the EMBASSY Trust Suite once installed by the user will be integrated into the Microsoft Office applications.
Note they are referring to Office (Word, Excel, Outlook etc.) and not Microsoft Windows.
So I would conclude that if I have a TPM on my computer and then choose to install the Embassy Trust Suite, the drop down menus such as File, Save will include options for things like encyption and offsite document savie/retrieval.
Just like many other applications, for example Winzip, can be integrated into the Office environment - it doesn't really mean any huge Microsoft revenue sharing relationship has been established. There are many applications that can claim to be integrated into the Microsoft Office environment. It means that you can choose to use these Add-On tools seamlessly from Word, PPT, Excel, Outlook etc. without opening another program such as Wave's Personal Information Manager directly via the Start-Programs path.
