[vbox-dev] stream optimized vmdk file layout??

I know this is more one for the VMWare folks, but since (a) Virtual Box
supports importing .ovf, which include a vmdk file in 'stream optimized
format' and (b) I am already subscribed to this list, I thought it worth
VMWare's specs on VMDK disk layout (e.g.
explain that for the stream-optimized variant of vmdk disks, the first
'compressed grain' follows the descriptor.
However, in .vmdk files produced by the 'packer' tool (http://packer.io)
it appears that the first grain's data does not follow the descriptor,
but rather sits in the sector of the file after the number of advertised
'overhead' sectors (a field in the sparse extent header).
Any one shed any light on this?
