On the workflow chaining, it is something I already do with NxBre where I tie multiple rule files together so I have a vested interest in trying to make that work.

Glad you asked. Was already thinking about that after I posted my comment. Here is a short stab a list. Keep in mind I am completely new to WWF. Some of these may actually be simple. 

 -Passing in arguments

-Dynamic Workflows

-Flowcharts, and other complex workflow objects (For example, WTH is the CompensationActivity? Docs are very poor in explaining what this thing is)

-Loading workflows from alternative sources( DB, UNC, etc )

-Error handling in a workflow

-Workflow chaining(not even sure this is possible)

-Synchronization with parallelism 

-Workflow Services

Sorry if any of these are simplistic. I am still reading up on workflow and what it can do.

Loved this. I did the lab on Friday. I found it by accident, but it really helped a lot. I would love to see an advanced lab as well dealing with some more advanced to medium topics.
