Rick Leir commented on GUACAMOLE-168:

My experience is with NoMachine NX client, connecting to a server across town. 
Response was snappy! Better than what I have seen of RDP. So I will be happy if 
we can get NX communications into Guac.

cheers – Rick

> It's been frequently requested that we add support for a more efficient 
> protocol like NX or X2Go. Though that sounds nice on the surface, and 
> theoretically would allow us to leverage some of Guacamole's nicer 
> protocol-level features, investigating deeper reveals:
> # X2Go *is* NX - it uses the same protocol behind the scenes.
> # NX isn't really a protocol - it is essentially a compressor for X11, and 
> depends on the client having a local X11 server to handle the decompressed 
> result.
> Implementing support for either of these would thus involve implementing 
> support for X11, which is crazy. *However:*
> What about implementing a driver for the X.Org X11 server?
> The X.Org server provides a driver abstraction layer which exposes access to 
> windows (including their hierarchy) and pixmaps, much in the same way the 
> Guacamole protocol provides nestable layers and buffers. If we were to 
> implement a Guacamole driver for X.Org, we would be able to make much greater 
> use Guacamole protocol features like client-side compositing. Operations 
> which are typically expensive in VNC or RDP like window movement suddenly 
> become simple, as they only involve updating the properties of a layer.
> I have an experimental implementation of all this, built upon several other 
> improvements which ended up being required. Work started several years ago, 
> even before Guacamole was accepted into the Apache Incubator, but I think 
> it's finally ready to move forward. I've been using it myself for roughly a 
> month now, and so far so good.
