i got to know about adobe air through yahoo sideline and tweetdeck.
i have two questions:
1) can adobe air app be deploy on web server and run from browser?
You can run an Adobe Air application FROM the browser.
But you cannot run an Adobe Air applicatin WITHIN the browser.
Indeed, Adobe Air wraps webkit (a very famous html rendering engine).
Think of Adobe Air as a shell built around an browser.
If you want to run something within the browser you can go with Flash/Flex.
