This is cool stuff, guys. Using JSON means you can put the authentication in the HTTP request, split up the services between various platforms, proxy out the web apps to any kind of tech, and scale the page load performance in a hardware-agnostic fashion.

I wrote someting a few years ago with JSON. IMO, it's way better than that old XMLHTTPRequest stuff. Done correctly, it really makes this web-as-a-platform thing sing.

Very cool stuff.
