The format supports sparse disk images. It does not rely on the host

Are these so important? Do people really pass VM images around with
http?
Absolutely. Part of the problem is that there's an industry expectation
that virtual machines are stored in images.
Even when you look at something like VMFS, which is a filesystem
designed specifically for virtual machine images, you still use VMDKs on
top of VMFS.

Maybe it's enough to teach scp about sparse files instead.
