David,

Thank you for the example; that really helps!

1) In servicecall/model2.xpl, for the output of the pipeline to be
usable by the PFC, it needs to be named "data".
2) I would discourage you to use the delegation processor, as it is
not maintained anymore. Instead, use the XForms submission processor,
which reuses the xforms:submission.

Here is the updated model2.xpl: http://gist.github.com/315242
And the result indeed goes and comes back from the service:
