Replying to myself because the OpenGL link is wrong. I meant this.

Are you implying that intercepting the DirectX or the OpenGL command stream is not a legitimate way? There are always different ways to do something, until one comes up with a better way. After that everything becomes obvious. About ditching X, I don't remember NoMachine to have ever been very active in the X development. Maybe they had come to the same conclusions long time before, but, you know, X was what was used on Linux...

This seems a bit unfair for people that, with their open source work, sparked at least a dozen of clones. Anyway if you are talking about dxpc, the compression NX is famous for has little to do with the original dxpc differential compression and is all about caching, that was completely novel and absent in dxpc.

I don't know what the secret sauce is, but AFAICT it is quite usable here. Fortunately now that xpra, NoMachine, OnLive and NVidia have all settled on the same technology we'll see who will provide the best solution. I think a remote display system is much more than encoding the display, so there is probably space for everybody. I just don't think one should badmouth other software to push the solution one likes more.

Do you have any proof of that? AFAIK there is very little remained in NX about the original X Window roots. They have ditched X completely even before Wayland developers decided to do it. While they have terminal servers for Linux that use X, the new version works on windows and mac and uses video encoding everywhere. This is no different compared to what OnLive or the NVidia Shield are doing.

Mandrake is also including it in the upcoming 10. See MandrakeLinux 10.
