  The draft seems to suggest that it occurs whenever an article is
received that doesn't meet the receiving site's criteria. One worry
that I have is that it won't work very well with streaming.

  Agreed.

  The problem with a seperate connection is that feeds may not quite
work that way. Right now, it isn't unusual to have things like:

	--> ispinfeed --> ispoutfeed
                   ^        	|
		   |		V
		  customer news box

   Sometimes ispoutfeed is feed using the INN SLAVE feature.
   Now, which host does the customer news box connect to? Obviously,
ispoutfeed. Sometimes the feeds are split based on hierarchies, so
one winds up contacting multiple feed machines for cross posted
articles. Not a big deal, but something that needs to be clear.
