Please see Rhinode II
The aim of this project is not to be a 100% node.js compatible implementation on Rhino (although it might go that way). There are other projects that attempt to do this (one is "rhinode" hosted on github as well).
The implementation is pretty straightforward.
More performance testing. Apache Bench is very limited.
Implement some real-life examples. (The canonical application seems to be a chat server :) )
Full FileSystem API
Clean up the code
Better name? Currently it's a combination of Rhino and Node (not very clever...)
