Aaron, John: ping, again.  The conversation about this branch has been 
stalled for ages.

[Here's my quick comments from my last ping:
"""
Some quick 2c from me:
  * HTTP at least makes it possible to put a bundle at a URL ending in /. 
I don't know if we care or not.
  * the change of handling to ConnectionError sounds reasonable to me, 
although I haven't looked at it very closely.
