spice != tv.  No multicast here.  Oh, and udp/multicast doesn't improve
performance, it reduces the bandwidth needed.

Not just the missing frame, but any video data until the next key frame
arrives (except for mjpeg).

No.  It would in increase the bandwidth needed as spice would have to
send keyframes frequently to compensate for possible packet loss.
