Ok, so Outlook 2010 has been out for a while now and I haven't heard anybody talk about the new "Social Connector for Outlook". It seems to me that the ZCS connector for Outlook ought to take advantage of some of the functionality of this feature, e.g. the pictures of users (perhaps stored in the GAL), and other such updates.
Are there any plans to integrate ZCS with Outlook in this way? If not, I am open to filing an RFE on bugzilla.
There also appears to be documentation online for developers: Microsoft Outlook - Developing a provider for the Outlook Social Connector version 1.1
