Thanks for taking a look at this. For my need the prefered behavior is a=20=

data stream because some files will be saved on disk
and other file will be only loaded in memory with other data already=20
there and later all the application data will be saved
to disk. For a more general view, I think the data stream is more=20
flexible and big file over internet is not often seen.

I will see how this is implemented, this is allway interesting, but I=20
think that this would be hard for me to implement a good solution.
