I started using TextMate for Cocoa a month ago. I still use XCode for managing project - adding files, changing settings, targets and so on, and I also still have to use XCode for Build&Run, which I've heard is possible to use from within TM (apple-r). Unfortunatelly I get error when building in TM, something in lines as if the target is not found.

As I can't make it to your talk, could you please post a small article about your experience with TM-XCode integration?
