i posted the ZipCheck demo live this afternoon.

this demo shows how use HTTP w/ REST constraints to build apps that offer immediate feedback to the user without using Ajax or other pipeline services. In this case, a US ZIP code validator is implemented as a URL. enter a valid US ZIP code (35004) and you'll see a green checkmark. enter an invalid code (99999) and you'll see a red "x." it's a smart idea. use the image/png content-type as a return representation of valid/invalid! i can't take credit for this demo. while my implementation using exyus is new, the idea for this came from this example.

anyway, the new demo is up and running nicely.
