The other big problem with this is video files - in particular huge 
ones. Using your document API loading a 1GB avi file would need 1GB of 
RAM which is of course completely barmy. Now video files are documents 
are they not? And they can be on non local media so theres another good 
reason for making the document API a subset whilst providing alternate 
methods for streaming files chunk wise.
