Actually spice-vdagent is almost OK now, only the init script need
some more test.
But spice-vdagent depends on spice-protocol, before spice-vdagent
enter Debian, spice-protocol should enter Debian.
Could you please upload spice-vdagent to mentors.debian.net? I'm using your packages with a recompiled kvm package with great success, having spice-vdagent would be the icing on the cake.
