Rival node.js RPC project (dnode) author chiming in here.

This is pretty neat and I like the emphasis on getting stuff going in as few lines as possible but I'm not convinced that return values and implicit result callbacks are the way to go for asynchronous requests, which is how I understand this project to work. Often when you want to make a remote call you'll be doing some I/O on the server side, which in node is asynchronous so you can't return right away. Passing along a callback from the client side works much better when the I/O actions have some values to call the client back with.
