on AIR Bus Tour Boston: Business Class AIR
Charles Freedman gave a couple of demos for Saleforce.com and Ribbit.
Salesforce provides a set of AIR specific classes to ease creating RIAs which leverage the data in Salesforce. AIRConnection.as is the main class which provides a layer between Flex and the AIR database which is based on SQLite. Looks like registration is required to get access to the toolkit.
Showed an example of how to use the AIR URLMonitor class to detect online and offline status. When online the sample application pulls data from the online database and caches it locally. Can then run queries against it and queue updates while offline.
Fully functional Flex based phone that allows adding telephony to any web page. Online version allows you to listen and read voice mail (they do some speech recognition). The AIR application downloads your call history to allow displaying it offline. Didn't feel like a convincing use of an offline application since it didn't look like it cached voicemail (even the transcribed version). He gave a live demonstration of calling someone in the audience.
