DHT specification questions

Hello,

The LimeWire specs for the DHT are a promising start, but after reading
them a looking at how I would implment something inter-operable, I have
the following questions:

* What is the current version of the DHT? 0.1?
* What is the layout format for the message fields with nothing explicitly
  mentionned? big-endian or little-endian?
* What is the format of the "DHT" GGEP extension in pongs? (this is not
  mentionned in the documentation, but I see a payload of 3 bytes).
* What does the "DHT" GGEP extension in a Gnutella pong mean?
* What is the SecurityToken? How does one compute it?
* For Gnutella usage, what are the values stored in the DHT?  What is their
  format? TEXT?  How is it determined what one should store in there and
  under which keys?
* What are the Kademlia parameters? alpha (3?), k (20?), b (5?),
  expire (86400?), republish (86400?), refresh (3600?), replicate (3600?).
* What did you choose as the data TTL depending on the distance to the key?
* Should a non-LIME servent store LIME-type data? TEST data?
* Is there a limit in the length of the values?  Would 1000 bytes be fine
  as an upper bound?

Thanks,
Raphael
