[chord] Questions Using Chord

[Brian Badillo]

I am a graduate student enrolled at Virginia Tech.  I am taking a course on 
distributed systems.  
This semester I have undertaken a project involving your peer-to-peer lookup 
service.  
I wanted to ask 3 things about Chord.

1. Where can I get started?  
I've been perusing the CVS repository and can't find any comprehensive 
documentation on the Chord API or examples to work off of.  If you could point 
me to some examples of code that uses the Chord service I could model my 
project after those.  Or if you could give me a quick rundown of what parts of 
the files on the repository do what that could be helpful too.

2. What exactly do I need for the peer-to-peer lookup service and what stuff 
is extra?  
I found some things that I will probably not need for my project such as CFS 
stuff, and some things that I'm not sure I need such as the Dhash stuff.

3. What happens when a node crashes unexpectedly and a request for a key on 
the crashed node is made?  Does Chord acknowledge the failed node and return 
the predecessor or is an error code given with nothing else or what?

Attached is my project proposal for the semester if you are interested.  It is 
a distributed game titled Jail Break.  
For the most part, I only need to set up the key space, transfer object data 
from node to node, and lookup nodes with keys.

Thanks in advance
Brian Badillo
