Exactly, since this needs some client side daemon this belongs in the existing
spice-agent, not in some new daemon. We could easily add new agent messages
+ capability for this. Note that since these files can be big we need to
be able to deal with sending files in chunks, so that other agent messages
can still get through at the same time.

I've actually been thinking about adding client -> guest support for this
for a while, we could simply make a file dragged to the client show
up on the guest desktop. Note that for large files we will want to
show a non-model progress window with a cancel button, something else
which the new agent messages will need to handel (cancellation).

Patches very much welcome !
