This is ultimately more important to Piper than it may first appear.  The
initial impression that most people may get of Piper is that it is a system
for /sequencial/ data flow (the data is passed to the next node only when the
current node is done).  If we didn't have Overflow at the core of Piper, this
may be true.  But Overflow is such a fast system that we want to include
/streaming/ data flow.  Here's an excerpt from one of Jean-Marc's (Overflow
developer) recent e-mails:

One may argue, however, that the lack of speed in transferring data across the
Internet makes this a futile goal.  But, we're ambitious, and things will only
improve :-)

Cheers.
