This file contains a few comments about our chord implementation. 
As with our other protocols, we requested comments from the paper 
authors before the release.  Unfortunately, Frans hasn't had the
opportunity to get back to us yet, so I will need to follow up
with him.  As such, there may indeed be mistakes in our chord 
implementation, which are likely our mistakes.

A few limitations:
- 32-bit hash addresses
- Fixed stabilize and fix-finger timeouts
- Recursive forwarding

We did receive a few comments from Ion, Thanks!
- It appears that the code implements only a successor list of size
two, right? Anyway, I think you should mention what is the size of
the successor list under "Notes:"
- In your code, fix_fingers invokes update_others. This is not
incorrect, but it is not in the original Chord pseudocode
in the SIGCOMM paper. update_others is called only when the node
joins. And then update_others is invoked for *all* nodes who have n
as a finger. Also note that in the ToN paper we have eliminated
update_others altogether. Again, the code is not incorrect, but I
would mention this difference under "Notes:"

Still waiting for comments from Frans et al.  Will follow up and add
to future releases.
