Ohhhh, yes! This sounds awesome, I've been meaning to write something like this myself. Essentially, a node.js equivalent, but for Cocoa. Of course, I'm way too lazy to add that to my work-load, but I'm very glad somebody did.
Now, if only I could use this in an Amazon EC2 environment. I guess with OS X Server supporting virtualization now with Lion, it might be a possibility?
I'm thinking about the fact that neither JavaScript on V8, nor Cocoa are equipped with HTTP networking. So the framework supplies that part. A big part of node, when used for a web app, is that it supplies an HTTP server. Same with this.
Cocoa (and CoreFoundation) actually make it pretty trivial to write HTTP servers already. I was completely surprised by how painless it was when I did it recently. Not quite as easy as Node.js, but on the same order of magnitude, IMHO.
