Hi again,
The features in the Alfresco Web Quick Start application that you mention (the stream asset directive etc) is not included Alfresco Share out of the box and there is no plan in doing so. I'm sure you will be able to configure it in, but it is not something that we know has been done before. If you want to try that I suggest you start taking a look at wcmqs-webapp-context.xml and also compare the surf-config.xml file in both apps but if I think it might be hard to get assistance if you run into trouble.
If you instead could write down exactly what you want to do I'm sure I will be able to give you an alternate solution in Share.
Cheers,
:: Erik
