I recently contacted sales to ask questions about Alfresco, as I'm currently looking into it over our current solution.
I also am looking at Flex integration, and although there have been announcements about some type of collab. between Alfresco and Adobe, nothing public has come of it.
In researching, I also found the 2.9B release that had the ACE and Flex-SDK modules, but there's zero information on how those are used, compiled and deployed into an installation.
I get the idea of using web-scripts to get content and what not, but it seems a bit overboard to write a ridiculous amount of scripts to mirror the capabilities of the repository, which already has all of these services.
The end result of what I'm trying to do is basically have full access to anything within a CMS system - create and modify users/groups, create and modify repositories and the content within them, and finally hook up Flash Media Server (Interactive Edition) to the CMS so that Flash video content may be streamed properly.
I found the authentication example, but have no clue how to deploy it. Hopefully Alfresco will provide some type of details on the new RESTful APIs and their service offerings for us rich client developers. I don't need an AS3 API… that's easy enough to create. I'm not a Java developer, so I just need to know where to get the info I need to make it happen.
