Wow, I wasn't aware that reCAPTCHA was now a Google owned operation. I will take a look at using that within Google Sites and then report back. It might take a day given other constraints, I will try my best to report back soon with the results. Thank you!

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.
