Today in keio University, Tokyo, Japan at W3C workshop on Ubiquitous web I gave the talk on device coordination with web applications. The position paper can be found here and presentation is hosted here.
The position is basically to standardize the interface to communicate with the security devices which are network addressable and are discoverable using standard discovery protocols such as UPnP, Bonjour or ZeroConf and are locally connected to the user's machine, from the web page and script from remote web site rendered by browsers.
