After browsing the website - it looks like this is a feature planned for their 1.0 release, due out this or next month.
My brief test on titanium was very favorable - ext runs well on it and it seems speedy and responsive (more so than IE or FF in any case). Coupled with native chrome and devoid of the other usual broswer issues (menus, toolbars, etc) this looks like it would be a valuable tool.
I wonder what they will end up charging for cloud services, packaging (a server side process) etc.
Titanium, like Air, does not support window.print() which I need in my apps. They are planning on adding support for it eventually.
Adobe does not plan to add window.print() to Air, and relies on Flex methods to print which means NOT using HTML to render printed reports (there are some horrible workarounds involving rendering the page as a bitmap, but the output is awful).
Well my initial expectation when starting with AIR was the production of a binary file, a SWF perhaps?, but I soon realized that AIR, more or less, acts like a local web server and browser in one.
I have been following Titanium since it's first announcement. After my experience using Appcelerator before that I am going to hold off until they are well past the 1.0 release before giving it a try, if they actually get to that point.
It seems that there is a technology gap for those who would like to create desktop applications using web technologies. Maybe something like Ext GWT for Flash is called for. Ext Flash?
After further thought I concluded that the more important part of my offering will be the associated "cloud" service therefore I think I will GPL the AIR app. Problem solved.
