John, As you know this is a hot topic in the Wf-XML area. We are currently looking at a RESTFul approach to it and I owe you a document (coming soon). Short of sharing the document that is currently half-baked, here is my current thoughts:
A remote engine is REST-accessible and any activity can easily launch a remote process. Calling activity would have access to remote process status & data (using a GET). Better, this calling activity could be exposed as a URI somehow and subscribe to process event notification. Calling activity waits for response, gets the message and continues on. This does not appear as a huge stumbling block... V/R, Pat.
