I have made a post on this subject in the other forum, but maybe this is the correct place.
How much Alfresco is really OSS? My basic concern is about JLan. I understand that the creator of JLan is Alfresco employee, but what about us ordinary people….
Since the CIFS is the functionality available in the publicly accessible version, how we should see its implementation (open for changes or not)?
All of the code in Alfresco in 100% open source. The portion of the code based on JLan (for CIFS) is also open source as the creator Gary Spencer is now an employee of Alfresco. If you can download the source from sourceforge, then it's open source.
The code is all open source. Our Enterprise customers have access to specific known builds and optional SVN access to specific known code streams - to ensure reliability and stability.
