So i have to admit that one of my favorite new applications is Screener. What screenr allows you to do is to easily, quickly and painlessly record a desktop session, whether you are on a Mac, PC, or linux computer using a java applet (which is pretty fast).

Once you record your screencast, you can then manage and administer your own channel similar to a Youtube or Vimeo channel. You get the benefit of a sleek player that clearly distinguishes itself from the rest, simple and has basic sharing capabilities.

Here is a demo by Netuts of an editable list that takes advantage of HTML 5 and the localStorage attribute and works with compatible browsers.

This allows you to create, edit, update and delete elements, and keep the state of the browser even after you refresh the page. This used to be done using either a database or cookies but the nifty use the new localStorage:
