yes it's a demo. And this UKIjs is 0.0.1 as per their site. But nevertheless, the demo on their homepage (hwlloworld button) impressed me. It souunds way simpler than Cappuccino or Sproutcore. Because Capp and sproutcore need config. But this sounds like, just embed the js directly in the page and it generates the page elements. Anyway, what it actually becomes/transforms into in the next few months will be interesting. I'm looking for an alternative to Sproutcore/Cappuccino that's not complex and needs little config and files (like one file jquery includes) :)
