I don't think I implemented the stream attributes for Charles, but it 
wouldn't be hard to do that.  Let me know which containers you need, and 
I'll give those priority.  See the charles-*.ad[sb] files in:

http://charles.tigris.org/source/browse/charles/src/

Note that the AI-302 containers are required to support streaming, and so 
the reference implementation has already implemented the streaming 
attributes.  See the a-c*.ad[sb] files in:

http://charles.tigris.org/source/browse/charles/src/ai302/

In either case, that means you can have a container of containers, and 
streaming it out will do the right thing,
