> BinaryValue should have a method get the unique identifier (if one is 
> available). That way an application may not have to read the stream if that 
> value is already processed.
> When the DataStore is used, a unique identifier is available, so probably 
> this feature is quite simple to implement.
> See also http://www.nabble.com/Workspace.copy()-Question-...-td20435164.html 
> (but please don't reply to this thread from now on - instead add comments to 
> this issue).
> Another feature is getFileName() to get the file name if it is stored in the 
> file system. This method may need a security mechanism, for example 
> getFileName(Session s) so that the system can check it. In any case the file 
> should not be modified, but maybe knowing the file name is already too 
> dangerous in some cases.
