I've been asked to create a desktop application for a website speed test widget, would Air be suitable for this? The thing I am concerned about is that the runtime has to be downloaded before Air applications can run, is there an auto-installer that can be packaged with the file so the user doesn't have to download the runtime package separately?
You can use a "badge" to install both an AIR application and AIR, if needed, from a web page. Adobe doesn't provide a separate installer that installs both, but you can create your own, as long as you sign up for the AIR runtime redistribution agreement: http://www.adobe.com/products/air/runtime_distribution1.html. (You will receive documentation and some helpful tools when you are approved for the program.)
Thanks Joe that's answered my question nicely.
