I'm fairly sure that compressed RAW is not much larger than sparse-file formats
like qcow2, so the file size should not be a problem for transmission, but
potentially for unpacking at the user's end.  I agree though, sizing the
underlying virtual disk to be quite small is a good idea.   Users can attach
additional virtual disks if they need more capacity.  It might be wise to use
LVM between the virtual disk and the filesystem, so that users could add
additional PVs and grow the root filesystem if required.
