Sorry if these have nothing to clarify the spec, but i was wondering: 
WHY using Kademlia for Bittorrent dht ?

1. This is one of the structured P2P systems with the least number of 
papers/analysis. Moreover, i haven't stumbled to any formal/detailed 
evaluation of this protocol yet.

2. Pastry offered the same functionality as it exposes DHT interface. 
Plus, Pastry has been studied in detail and its routing has very low 
latency: median of 1.7 compared to the optimal IP latency. I believed 
Pastry is one of the best DHT systems out there, and it is definitely 
not close-sourced. Tapestry is also good.
