Thanks for clarifying. No, I do not want to manipulate the token from the other thread. I figured that was a no-no. From my other thread I just want to know what node it is on. We want to provide users with some insight into what state the workflow is in.

In this case I think it is acceptable for the user to only have visibility into the previous rest state of a process. Any "long running" step in the workflow should be done asynchronously... the node should post some external request, and wait until that request has been satisfied.

If the workflow is marching along through some simple nodes that don't take much time (e.g. a decision node, or query to the DB) then the user would have to be aware that by the time they looked at the output of their request the workflow would already be beyond that point anyway. Probably at the next wait state.

At least that's my thought. Please let me know if I've said anything that doesn't sound right.
