I started the download part and the stream driver quite a while ago
but stopped and put it aside as I realized that the storage volume
API up- and download functions assume one file per volume. This is a
problem with ESX as a VMDK can consist of two files. To solve this
now I added two new flags: METADATA and CONTENT. With this flags the
user can specify which part of such a volume to transfer. See patch
3/3 for more details.
