Could you please report any results of further experiments ?

 
After a busy few weeks, I finally had time for this again. I tested the
below, just now, and it seems to work, more or less. The $href provides
the XForm URL to the p:exec that simply runs a browser with it. The
XForm includes a save of its result to the file system but right now I
need to close the browser before the pipeline knows it is OK to move
on.
 
Pretty cool. :-)
