 ## Further development
 
-* VNC support.
 * Alternative folder sharing support (NFS or SMB).
 * Remount 9p shared folders and reinitialize spice-vdagent upon resume from disk [see possible bug](https://bugzilla.redhat.com/show_bug.cgi?id=1333072).
 * More params (memory, cpus, ssh, serial console, additional shared folders, etc).
