Hello,
We are French ISV's and we think that it would be a great thing to deliver a SDK for SharedView.
We would need to create create dynamics sessions and invite people to work with us, directly from our apps (not only from Office and either Windows and/or Web apps).
By this way, it would be easier for us to "create the need" of a Sharepoint usage or Office 2007 migration... (most of our customers are still using XP/O2003.)
We think that it's not Office 2007 that will make users use tools like ShareView but tools like theses that will make users use Office 2007. (it's the same for XP to Vista)
