+Note on spice: Spice handles multihead just fine. But it can't do
+multiseat. For tablet events the event source is sent to the spice
+agent. But qemu can't figure it, so it can't do input routing.
+Fixing this needs a new or extended input interface between
+libspice-server and qemu. For keyboard events it is even worse: The
+event source isn't included in the spice protocol, so the wire
+protocol must be extended to support this.
