Check out the sample and code walkthrough at http://kashyapas.com/2011/05/releasing-netflix-catalog-using-htmlodatadatajsjquery/.

Some highlights:

• All the app components run in the browser!
• Clever use of the datajs cache - those values aren't changing anytime soon, and it definitely speeds things up to avoid round-trips. Nice way of reducing the page startup time.
• Templates are stored as plain text files on the server, then retrieved at runtime when the page needs them - again, clever!
• A server that opens up its data for cross-domain access enables some very, very powerful scenarios.

The code is available on CodePlex and is short & sweet. Enjoy!
