Splashtop

Splashtop initiates the new generation of remoting. It's like VNC but with sound, and so much faster with such a low latency that you can even play video games. VNC should have evolved this way long ago.

This a partially closed source shareware which is its main problem especially with regards to security. It is designed so that you can use your tablet as a screen to your computer.

It still misses a lot of platforms but it is currently rapidly evolving over the course of a few months.

Inconvenient : you need a SplashTop account which you can currently only create with the use of a tablet.

My current tests : streamer (beta) on Ubuntu, client on android iconia tab over a wifi local network.

Positive points : -Impressive performance

                          -Very responsive.

Negative points : -usb keyboard by default only partially supported (although it maybe because of the tablet) ; in particular the navigation keys (which are supported through VNC on the same tablet)

                            -real mouse supported in an unintuitive fashion.

                          -Stability problems (but it's only beta), if you don't have a fix ip, it will not work for a long time, you will lost connection without being able to reconnect. Some keyboard input on the client make the streamer crash. It crashed 3 times in 30 minutes. It sometimes even crash the unity desktop when used in conjunction with x11vncserver.
