New in Sametime 8 is the ST Helper toolkit. The toolkit is basically COM interfaces into the Sametime client, allowing you to start chats, resolve users, watch users etc.
Sadly this toolkit requires the Office integration to be installed.
I believe this toolkit functionality should be part of native Sametime client, and shouldn't require the office integration to get to it. Especially if someone wants to code things into Office and not use the Sametime Office integration.
