We've release the 0.5 version of the Intel Web 2.0 TDK (available for download at http://software.intel.com/en-us/articles/intel-web-20-technology-development-kit-tdk) The name is bit a misnomer and reeks of marketing It really targeted at AJAX-based applications.
It's not perfect and has a lot of gaps and warts, but we wanted to get it out so that we can get some feedback. There's a pretty good discusion about the TDK on Ajaxian (http://ajaxian.com/archives/intel-web-20-technology-development-kit-tdk#comments)
Give demo video a look. It demonstrated the basic functionality of the TDK.
In the near future we'll be releasing an update (v0.6) which cleans up a lot of the code and docs. Another, thing we're adding is widgets. These are prepacked gauges (battery, processor utilization, connectivity indicators) that can be embedded in a web page with a single line of code:
PowerIndicatorExample = new powerIndicator( ... );
I'll be posting a video that shows it in action
I'm interested in hearing your suggestions, concerns, and comments. We're very early in the project so this is a good time for input.
