The company I work for is in the digital signage space. We would like to build a module in our Web Application that allows our customers to author/create/build flash content which will then be used on their signage units.
Is this possible with Flex/AIR/Flash. Meaning, are their controls in the SDK's that will allow me to create an application that creates flash content?
I think you have the wrong idea. The better approach is to write an application to allow your clients to create the content and then save it perhaps as an XML description. You then write a Flash/Flex application to read that description and recreate the content.
