The poor man's VNC. If you have ffmpeg and netcat you can stream your screen across your network with two one-liners

ffmpeg screen sharing
# If the server has ffmpeg:
## For the server:
ffmpeg -f fbdev -i /dev/fb0 -f avi pipe:1 | nc -l -p 1234
## For the viewer:
nc 127.0.0.1 1234 | ffplay -i pipe:0
# If the server doesn't have ffmpeg:
## For the server:
sudo cat /dev/fb0 | nc -l -p 1234
## For the viewer (replace 1920x1080 with the server's resolution):
nc 127.0.0.1 1234 | ffplay -f rawvideo -vcodec rawvideo -pixel_format bgra -video_size 1920x1080 -i pipe:0

Version that doesn't require root.
Server:
ffmpeg -video_size 1600x900 -framerate 25 -f x11grab -i :0 -f avi - | nc -l -p 1234

change 1600x900 to screen size, and framerate to whichever you desire.

Client:
nc 127.0.0.1 1234 | ffplay -i -

change 127.0.0.1 to the IP of the Server.

Tested on Ubuntu 14.04, Ubuntu 16.04, and Linux Mint 18.
ffmpeg 2.8.11
