Hi,
Can you explain/exemplify, why sending data as a blob (either by (a) or
(b)), that is verified only by the two ends that actually use it, is a
problem?
It tends to be not very robust. Especially when the creating/parsing is
done ad-hoc and the format changes now and then due to more info needing
to be stored later on. The qemu migration format which has almost no
structure breaks now and then because of that. Thus I'd prefer to not
go down this route when creating something new.
cheers,

Exposing spice server internals to the client/qemu seems to me more
vulnerable then sending it as a blob. Nonetheless, it introduces more
complexity to backward compatibility support and it will need to involve
not only the capabilities/versions of the server but also those of the
qemu/client. Which reminds me, that we also need capabilities
negotiation for the migration protocol between the src and the destination.
