Personally, I'm interested to see if this can become a central point for collaboration across all Autodesk products and services. On a wider scale, I'm keen to investigate any collaboration tools that allow quick and easy discussion of "issues" - when I say issues, I mean "anything that needs to be discussed and solved." AEC teams have these kinds of discussions throughout the entire building design and delivery process... but there isn't a nice, clean, easy solution to manage all of those issues and conversations (yet). I can picture it in my mind, I just haven't seen one in real life (yet).
