P.S. So i had a quick look at that WAPI spec, and it looks like
workitems are referred to using a process ID ('wfid' for OpenWFE), and
a workitem id, for which there doesn't seem to be a corresponding
concept in OpenWFE.

So why is there no way to directly refer to a in-flow work item in
OpenWFE? It seems to me like this would be useful... I send some data
payload into the process, and later on I want to know where that
payload is, what it's doing, etc. based on some payload-identifier
(i.e. workitem identifier). From what I understand, right now I can
only refer to the workitem indirectly by knowing a the workflow
instance id and a participant name where the item might be sitting.
And the process for doing this is *really* indirect... something like:

- get ProcessStatus of some running workflow using wfid
- get list of expressions from process status
- get fei(s) from these expressions
- somehow knowing the list of participants in the workflow, check each
participant using the fei to see if the workitem is there....
- then finally get workitem from participant

Oh man. I must be missing something here?
