Please create a demonstration / example that shows a scatter/gather webservice use case

To help others, like myself, see where GPARS is useful in the middle service tier of a SOA environment, it would be great to have a GPARS WebService example. The example might be a few trivial services and them another service that sends off two or more requests to other services, waits, and gathers the responses, sending the final aggregated response to the caller.
